Samsung worth the headache?....... You decide
I have been a loyal Samsung customer for years. I have dozens of their products and when I entered the market to buy a SSD for my computer I was pleased to be referred to them as one of the top names for SSD's. My headache began as soon as I started the drive and initialized the 'Data Migration' Software to copy my existing Hard Drive so that I would not have to reinstall OS and all my programs. ( I do not mind doing this, but prefer not to if I can help it ). Right after the drive cloning was complete and I had successfully restarted with what seemed like no problems I was thrilled with the boot speed ( roughly 3x faster than my old hard drive ) from powered off to loaded desktop in solid 20 seconds. Fantastic. Then I proceeded to launch a game and test out some load speeds. I started receiving blue screen windows crashes ( too this day I had NEVER had ONE on this computer) and could not pinpoint the cause. Since this was the only new piece of hardware in my machine I started with the drive. I was unable to confirm exactly what when wrong but within 3 days this drive had become the bane of my existence. Every program I would attempt to run would crash. Nothing could load on it and I started getting constant errors for any and everything under the sun. (I even got an error when I attempted to shutdown?!) finally the drive just stopped all together. I then began to get an error on my motherboard. After contacting EVGA customer support I was guided to reset my CMOS. Cleared my issue and then had to diagnose what the heck was up with this drive.This drive was inoperable after my reboot. Whatever the final straw was set this drive into what Samsung calls a 'frozen state'. This drive also came with another product called Samsung Magician which helps optimize to drive and customize certain settings but also allows the user to do a 'Secure Erase' on the drive to wipe it to factory defaults. Apparently for whatever reason you are not suppose to reformat the drive within any other program as it can wipe certain factory settings off the drive leaving you with a pricey paper weight. Since this drive was inoperable at this point I had to reformat and reinstall windows on my old hard drive and get to a working version of windows so I could fix my drive through Samsung Magician. --Skip ahead 3 hours -- (HEADACHE) Samsung Magician cannot secure erase the drive while it is in a frozen state. (figures!)There is a process it guides you through in order to 'unfreeze' the drive. While in windows the process did not succeed for me. The second option to unfreeze guides you to load a DOS program on a USB stick and restart the computer and boot from the USB stick. I changed all my options in my BIOS and for whatever reason this would not work. It was suppose to run the DOS program after exiting BIOS and would never work. (headache continuing). On to the third option of clearing frozen state! instead of USB stick you need a disk (CD or DVD) that is blank and burn the program onto. Thankfully my last option worked! but..... the DOS screen looked more like a garbled frozen screen of hieroglyphics. I had found a forum online that discussed how to reset it. It suggested that while at the garbled screen hit 'ESC' to pull up a DOS command line and enter SEGUI0.exe . well all that does is restart the program which is still garbled. after a call to Samsung's customer support they told me the issue is that with newer video cards the screen cannot display correctly unless you type SEGUI0.exe /s . IT WORKED. happy day. finally we are getting somewhere. The program that is running is just a DOS version of the secure erase function from windows. it runs before you computer has booted. you need to have the option in your BIOS turned on for 'hot plugging' whatever connection the drive is plugged in for the next step. it tells you exactly what to do and will guide you to PULL THE POWER CORD ON THE DRIVE WHILE THE COMPUTER STAYS ON. Then replug in the power connection after a few seconds. then restart the application with the previous command you entered. The drive FINALLY unfroze. I had to secure erase because there was no freaking way I was going to clone the drive again. (I am fairly certain the excessive amount of errors were coming from improper cloning of the system files for windows) Doing the old fashioned way with an OS disc install directly onto the drive. ---PLEASE DO NOT MAKE THE MISTAKE I MADE HERE AS IT WILL COST YOU SEVERAL HOURS OF YOUR TIME TO FIX--- WHEN YOU GO TO INSTALL WINDOWS WITH THE OS DISK DISCONNECT ALL OTHER HARD DRIVES I did not do this and did get the drive working but after some testing realized that it was using the system reserved partition from my old hard drive to boot because windows did not make its own system reserved file on my new hard drive. And with several attempts I could not figure out how to clone the system partition over. Also when you are selecting the drive to install the new OS onto click on the drive and click the button at the bottom that says 'advanced options'. 3 or 4 more options should come up. CLICK NEW and it will tell you it has to secure part of the drive space for windows functions. It should create the partition right there in front of you that will read on the screen as 100mb in size. THIS IS THE SYSTEM RESERVED PARTITION YOU NEED TO BOOT THE DRIVE BY ITSELF. after you see that continue on installing the OS until you are all updated and have all your programs re downloaded. Then you can shut off your computer and reattach your other hard drives (if you have any). If you computer decides to start thinking for itself it may try to boot off of other drives, just goto BIOS and select the new drive the be the first in the BOOT priority. So after 2 re installs of windows and a lot of consideration for introducing my hammer to my SSD I did finally get a usable, NON ERROR forming drive that is fantastic. Perhaps some people did not have this much trouble but I certainly did. One note I would throw in. As of my current install I don't even run the Samsung Magician Software anymore. seemed to be more of a headache than anything else and my drive works fine without it after my old school OS install. All and all I am still happy with my purchase even with all the trouble shooting, in my opinion it shows the value and quality of this drive that It can recover from just about anything..... except maybe a smash from a hammer. I really doubt you should have any kind of compatibility issues but in case you specs are close to mine you may purchase without worries. My computer specs are: --Intel I5-2500K (Sandy) Processor --EVGA Z68 ATX DDR3 2133 Intel - LGA 1155 Motherboards 130-SB-E685-KR --EVGA GeForce GTX760 FTW with ACX Cooler 4GB GDDR5 256Bit Dual-Link DVI-I DVI-D HDMI DP SLI Ready 04G-P4-3768-KR --2x--Kingston Technology HyperX 8 GB (2x4 GB Modules) 1600 MHz DDR3 Dual Channel Kit (PC3 12800) 240-Pin SDRAM KHX1600C9D3K2/8GX --Windows 7 Home Premium SP1 64bit (Full) --Samsung Electronics 840 EVO-Series 250GB 2.5-Inch SATA III Single Unit Version Internal Solid State Drive MZ-7TE250BW --Western Digital 500GB and 1TB Blue HDD (7200rpm) SATA III --Pioneer Electronics USA 15x SATA Internal BD/DVD/CD Burner with 4 MB Buffer BDR-208DBK --Sony AD-7280S-0B 24x SATA Internal DVD+/-RW Drive (Black)

840 EVO 250 MB upgrade to 4 yo computer Asus/AMD motherboard
I gave the unit 5 starts even though there were some problems I have not been able to overcome. I can't blame the problems on the drive as I installed it in a 4 year old home built PC, ASUS M4A 79XTD mobo, which has SATA II, and an AMD chipset. The BIOS has an option to enable the enhanced ACHI interface over IDE. ACHI has speed advantages for the SSD, and I get the BSOD when trying to boot using that option. It works fine in IDE mode, and it is still approximately 4-5 times faster than my Samsung 1T HDD. Boot time including starting the Firebox browser in Startup went from 4:13 to about 57 seconds. The drive comes with software that is instantly obsolete, I got the latest Data Migration, and Magician software off the Samsung site, the drive itself had the latest firmware. If you need a firmware update, the Magician software will do that for you. To install the drive I loaded a WD 250 MB HDD with a fresh install of Win 7 Ultimate, and a few other apps, like Firefox, but no MS Office, which loaded the WD HDD with 40 GB of data. The drive had all temp files deleted and was defragged. An external Thermaltake BlacX docking station used the USB 2.0 port to migrate data. The EVO SSD was recognized instantly by Windows with no problem, after using the Windows Disk Management program to partition and Quick Format the drive, which is well documented on Youtube. Data Migration is the first program you run, and it clones your HDD to the SSD. You have no choice here, it clones everything, or nothing. The data transfer was about 12 MB/s, my 40 GB drive took about 45 minutes to clone via USB 2.0. The SSD is then attached to the mobo using the old SATA cable, and it starts right up. Mine did not boot the first time and asked for the Windows install disk to repair the installation. After following instructions, it was fine. My drive would NOT boot using the recommended ACHI mode which I set in the BIOS. My ASUS mobo was stamped 2009 (four years old now) and ASUS tech support could not help me, and nothing from an extensive Google search helped me. The first 4 SATA 1-4 channels are controlled by an AMD chipset, and SATA 4-5 are Marvel. I now have the SDD on SATA 1, the Samsung 1T HDD (for data) is on SATA 5. Everything boots and works well, and is still very fast, even though I have SATA II and no ACHI. The Magician software gets loaded last, and will help optimize the drive and run speed tests. I did not run any tests, but the computer apps/programs are noticeably faster in every way. The drive formats out to about 238 GB, so don't expect the full 250 GB. In addition, to speed up and make the drive more reliable, Magician takes another 10%, recommended. After the OS was installed, there is another 200 GB usable. Some apps like MS Office will go on the SSD, and minor apps like utilities will be put on the 1T drive, as well as temp files and downloads. I bought the bare drive, so it was cheaper at about $140 for the EVO 840 250 MB drive. I had all the cables and docking station I needed, but I can see where the kit with the cable and mounting bracket for a desktop installation would be helpful. All of the few problems I had were anticipated because I did my research and read everything before buying, so there were no surprises and the drive works fine. When I am ready to upgrade the old mobo, I expect the drive will run at the faster speeds. If this is reliable and I think it will be, this drive is highly recommended.

excellent drive, hassle free installation
This is the third 840 EVO 250gb purchase from amazon in span of a month. I got one for friend, one as a boot upgrade for desktop and the most recent one as replacement for office laptop. Overall, my 5th SSD disk so far, the previous two being Crucial 60gb and Kingston 120 gb (both are working just great after 3 years now). By the way, if you are wondering why SSDs are great, a. they add few years of life to some old machines that you would have discarded b. They make boot times extremely fast, so that shutting down PC isn't a pain c. Windows performance benchmark score jumps from 5.6 to 7.9. Its 7.9 because I think it cant go up any further. d. For tech enthusiasts and IT professionals, try running your I/o benchmarks for use cases you need fast random read/writes and see how things speed up. For large sequential reads, the HDDs try to catch up. e. no need to do defrags, though you may need to do some maintenance like over provisioning, which I will talk in a bit. here are reasons I love this 840 EVO drive, besides the price - 1. Convenience - Biggest point in favour of this drive. If you are replacing your current HDD drive with this, it cant get any easier. Connect the SSD through a USB adapter to a USB port (not provided with this packaging). Install the Migration software, and just clone your drive. It worked for me 2 times in a row on a desktop and a laptop. then, just replace the drive, install magician (optional if you want most from your drive) and you are done. Migration Software takes care of partitions and clones the drive as is. However, if you are adding this as a boot drive in addition to your existing drive, then this will not help. You have to install the OS on this drive. 2. Speed - Honestly, there is as much difference between various SSDs as there is between the SSD and HDD. When you run benchmarks, things will be faster on this one, but on day to day stuff like booting, opening files, and a typical consumer type of a usage, it wont make much difference. However, if you are a tech or geek, this drive has one of the fastest read/writes I have seen. If you have plenty of RAM, you can use Rapid to do "look ahead reads" and increase read speeds over time. I tried thinking about EVO vs PRO and felt EVO was good enough for general purpose, plus some occasional high performance IT needs. 3. Noise & Size - after replacing this, the laptop and desktop went silent. you can hear just the fan. Though most current HDDs are silent too, this is 0 db. 7 mm is perfect for laptops and notebooks. I hope these last reliably as my earlier ones. Few tips on configuration. In magician you will see a bunch of options. If you want more from your Samsung 840 EVO SSD spend time going through them, they are not tough, and you will get to know through the prompts. I use over provisioning at default, switched my laptop from RAID to AHCI. Win7 and above know how to handle SSDs so you don't strictly need Samsung Magician.

Really helped to speed up and quiet down my desktop computer!
I'm replacing a noisy hard drive in a computer that already has one SSD. The existing SSD is an Intel X-25M (160GB), an older one. Since the Intel drive is already the C: drive, I thought that I'd add this one (250GB.) as my data/backup D: drive, same as the noisy hard drive. However, when I compared the specifications between the two drives, the Samsung and the Intel, I decided to migrate the OS from the Intel drive to the new Samsung drive. So, first thing after mounting the drive in the computer, I tried the Samsung data migration software. It put up a window saying to close all applications, and open files would not be migrated. Naturally, I interpreted that in my own unique way, and rebooted the computer into Safe Mode *smile*. Well, that didn't work, apparently some stuff that the data migration software needs is not there in Safe Mode, so I rebooted into full Windows mode and went directly to the Admin user without opening any other applications. Of course, the usual stuff was running, antivirus, backup to the cloud app was frozen at that time, etc. The data migration/cloning was a breeze, it just worked, no problems with unmigrated/uncloned files. Rebooted after that, and went into the BIOS to change which disk to boot from, and the system boot up and worked just fine, only faster. On the WEI (windows experience index *smile*) my disk went from a 7.7 to 7.9 (as high as it goes on Windows 7), and definitely feels faster and more responsive. Then I went and tried to delete everything off the former OS SSD, and ran into some problems, not being "trustedinstaller" *smile*. So I ended up booting from a Live Knoppix CD, and deleted the undelete-able stuff that way. Worked fine. Then restored all the data that was on the hard drive (D: drive) using my "backup to the cloud" app. That worked great as well. Did have some fun with drive letters, though, some little "System Reserved Partition" thingie had grabbed the D: drive letter during the data migration and first reboot, so I moved it to "L:", and moved the SSD that had been the C: drive to "D:", where the noisy hard drive had been. Since I have some apps that use "D:" for data files, this was the way that I needed to have things set up to have to do the least work *smile*. Last thing I did was to make sure that everything looked good with the Samsung Magic app, reminded me of the Intel SSD Toolbox. All good on both SSD's, performance all optimized *smile*. Anyways, very happy with my "new" faster, quieter computer. All I can hear now is fan air flow noises that are easily tuned out, instead of intermittent loud humming noises. I like my computer a lot more now, money well spent.

Great drive but not as fast as expected for a desktop
Was running Windows 7 Pro and had a copy of Windows 8 Pro that I was waiting to install until I upgraded to a ssd drive. Got this drive for a great price and was finally ready to pull the trigger. Did a clean install on this drive of Win 8 Pro and then moved my documents, photos, music and movies to a 1 TB drive. Optimized this drive for the operating system and did all the ssd stuff you are supposed to do when using a ssd with Windows 8 to optimize it. The good: Install was great. Took all of 7-8 minutes to install Win 8. The reboots for updates is very fast. Boot time is exceptional. I know this drive saved me hours when doing all of the upgrades to Win 8.1 Pro and installing Office, software games etc. When you first install software cleanly, including the operating system, it can take forever with all of the rebooting etc. So again, I figure I probably saved 5-6 hours conservatively using this drive. Threw my games, online games, and steam games on this drive and those installs also were blazing fast. The Samsung Magician software is nice and reports that my sequential read/write in rapid mode is 1154/1106 MB/sec. Certainly seems fast on the benchmarks but real world application seems a bit different. The OK (cause there is nothing really bad to report) Real world use for me is not quite as impressive as I thought it would be. My computer is also attached to my big-screen as a second monitor when needed for movies etc and this system stays on all the time. Because it is on all the time then the fast boot times don't really matter so much, which would probably be the same for lots of others in the same boat. This drive probably shaved off a couple of seconds for Firefox opening, but what is 2 seconds from 9 down to 7? Thought programs would open instantaneously. Browsers do open a bit quicker, but as I already had a fast system (using 2 drives with swap file at the beginning of my fast second drive), I have not really noticed anything that is eye-opening blazing fast. Games seem to load a bit faster, but as I mostly do online games, I am still waiting for the server and the other people to join, and so much of gaming is based on your internet connection and ping time. So while it seems a bit snappier, it still is not the speed demon that I had expected and waited on for all this time. Not much difference noticed. Conclusion: Working with graphic files, converting movies for Media Players and Tablet, and loading things in general seem to be a bit snappier. If you have an older system OR you plan on using this as your only drive in a laptop, then it would probably be a breath of fresh air. If you already have a fast system that is set up properly for speed, then you probably will only notice much difference when you are rebooting. Have to say, this is a great drive and if everything was on it and if I also did my mirror image of it or backups to another fast ssd instead of a flash drive or mechanical hard drive, then I am sure it would be impressive. Real world using regular hard drives in addition to this ssd and not rebooting often and having a speedy system already, I am not nearly as impressed as I had hoped to be. Thought I would be blown away, but after a month or so of real world use, I am still waiting to be impressed. I am sure I will be waiting until the huge ssds are affordable and will be the only type of drives in desktops. Then the full speed will probably be realized. In this hybrid world of mechanical and ssd and cloud and so much on the internet, Impressed..... not so much.

UPDATED: Accept No Substitutes (cache drives, dual drives, etc)
UPDATE 3/12/14: The following applies to the 750GB version of this product (just received 3/11/14) as well as the 250GB (which I purchased and reviewed first) For those wondering, the 750GB does in fact have 698GB of space (just like a "750GB" hard drive). That said, the ~9% loss here isn't because the drive doesn't have the capacity (like spinning platter drives), but because Samsung set aside 9% of the flash memory as over-provisioning to lengthen the drive's life. This is a _good_ thing! (That means the 250 = 233 for the same reason). I installed the 750GB drive in my Dell XPS 1640 which is a 2009 laptop. As I've discussed with my other SSD review of a Kingston product, modern PCs really only have one bottleneck for everyday use--the hard drive. I observed this in a quantifiable fashion under Windows 8.1 Pro x64 on my laptop. The SkyDrive/OneDrive agent was doing something at 11MB/sec and some Windows processes were hammering the CPU to 50-60% total usage (Core 2 Duo 2.53GHz). Yet the machine felt as responsive as if this simultaneous activity were not occurring. A sustained 11MB/sec operation on the old 750GB Momentus would have slowed my laptop to a crawl! Now, a lot of power users will just clean-install and won't need this, but I committed power-user blasphemy and employed Samsung's cloning software. To quote Admiral Ackbar: "IT'S A TRAP!" The software will apparently clone just fine, but can get "stuck" at 100%. Searching for the issue, I found it relatively widespread. The usual response from either Samsung itself (via Facebook) or other users (in several places) is "Let it sit for a bit, then cancel." Thing is, even if you "succeed" in cancelling, the "clone" won't work 100% due to the way (at least in 8) Windows handles boot files. Insert a Windows 8 install disk/USB (it's possible Windows Vista/7 media may work but I have not personally tested this and am not responsible for any damages if you use older media and hose your system). Boot from the media, click next when prompted for locale information. Instead of the big "INSTALL NOW," choose "Repair your computer." On the next screen, select "Advanced Options" then "Command Line." Type the following sequences in and hit enter after each. I'm not sure if they can be used in a different order, but the third command should definitely go last. bootrec /fixmbr bootrec /fixboot bootrec /rebuildbcd The last command triggers a search for valid Windows installations (such as your clone). It should find it and ask if you would like to add the OS to the boot list. Type "y" for yes. Let the computer restart. It should boot straight into Windows 8(.1). The procedure may also work to repair cloned Windows 7/Vista installs, as the boot setup is broadly similar to 8 in contrast to Windows XP. Please note that while I believe this information to be correct, I can offer no guarantees and will NOT offer support or answer questions posted to this review regarding the cloning process. Seek help at a dedicated tech support forum. RAPID Mode is worth enabling--things feel subjectively even faster. Yes, Samsung's RAM cache outdoes Microsoft's "SuperFetch" at its own game. For those concerned about endurance, don't be. Search "AnandTech Samsung EVO endurance" to see why in detail. The short version is that excepting the 120GB model, even at 100GiB (that's 1024MB/GB, 1024kB/MB, etc, or 2^30) of writes per day, these drives have at least 6 years of life in them (the 120 is fractionally under 4 years). By the time the flash memory fails, you'll be looking at a new computer anyway! I maintain the product's high rating of five stars. If I could rate the software separately, I'd give it three--it moved my stuff but messed up the boot sector. And it hangs at the end. BOO! END UPDATE When I first built a computer in 2006, 10k RPM hard drives were the only way to obtain fast boot and I/O performance. I started with a 150GB Raptor, then through several failed drives ended up with a 300GB VelociRaptor (as compensation for FOUR 150GB Raptors dying). That was a relatively responsive, quick drive. However, this EVO 840 leaves any mechanical drive in the dust! I have not experimented with RAPID and it is still blazing fast. I have a PERC 5/i RAID card and Intel Rapid Storage Technology RAID1--this SSD is so fast that I spend more time looking at RAID screens during boot than the Windows booting animation. The key measure of PC responsiveness to me is "When I see the desktop, can I use the computer right away?" Raptor: No. Samsung 840 EVO: Yes. Even after a bunch of apps (iTunes, Java, Adobe Creative Suite, Logitech, Samsung Magician, Windows Gadgets) added themselves to the boot, it is still incredibly fast with the same level of instant-response at the desktop. Even if you don't buy this solid-state drive, ANY quality solid-state drive will drastically improve your experience. Even a Kingston Digital 120GB SSDNow V300 SATA 3 2.5 (7mm height) with Adapter Solid State Drive 2.5-Inch SV300S37A/120G confined to SATA1.5Gbps will make a HUGE difference!

Perfect Performance, Reliability and Endurance For The Price (and for laptops)
I've had my eyes on this new line up of ssd's from samsung ever since they first announced it, not for the possible 1TB capacity version or necessarily the new great refreshing color: for the price/performance ratio. I've always felt that the plain 840s were too low on the write performance, not worth the savings compared to the closer to $1/GB and higher performing 840 pros. It felt like i'd have to get something way simple or way over the top, which neither felt right for my new Alienware 14 laptop and considering I put down $1500 for it. So, to the point, this 840 evo 250GB version packed just the right performance for a great price: Price: $182 + tax + $8 shipping AS SSD Benchmark Seq: 502mb/s read; 493mb/s write 4K: 37mb/s read; 97mb/s write 4K 64: 348mb/s read; 210mb/s write Acc: 0.086 read; 0.036 write AS SSD Copy Benchmark ISO: 322mb/s; 3.33 sec Program: 154mb/s; 9.03 sec Game: 163mb/s; 8.44 sec In real usage (boot, idling and you know daily use) the entire system felt faster and more responsive than with the s***ty sata2 HDD that came with my Alienware 14; plus the Samsung magician software also allows you to use rapid mode which uses ram as cache to increase writes by a CRAZY amount, surpassing 1000mb/s and putting reads at about 600mb/s. Its not very consistent though, but still very useful in the correct scenario. Only one issue I've had is that after migrating the files on the HDD to this ssd with Samsung's own software, when the ssd went to idle like hibernating or just turning off display due to no use after a few minutes it would not come back up, or if it did it would simply freeze everything only to be resolved once i held the power button, shut it down the hard way and then turned it back on and never allowed it to idle or hibernate. I've optimized the ssd by disabling indexing and some smaller tweaks but havent dared to see if these issues were solved, so i always shut it down after done with anything or when i know it will end up idling for lack of use. it boots fast enough for me to get it all back up again under 30 seconds so thats not a problem. Overall I'd recommend this ssd if you need the super high capacities and not have to deal with multiple ssd's on a raid environment or have a hard drive involved in your system, and/or if you need a balance between the 840 and 840 pro. Here's the pyramid for the Samsung ssd's: 1 - 840 Evo on RAPID Mode 2 - 840 Pro 3 - 840 Evo 4 - 840

VERY FAST, EASY install (UPDATED with iastor FREEZE/HANG FIX)
I got the 250GB Samsung EVO 840 for a client who wanted to upgrade their older computer's hard drive for better performance. Their old hard drive was a 250GB 7200 RPM WD Blue series drive which was over half empty. The older Dell Optiplex computer only has SATA II interfaces. The Optiplex uses caddies for the 3.5 inch drives. I got a SABRENT 3.5 to 2.5-Inch drive bay adapter which is supposed to work well with screwless caddies. The Optiplex caddy had to be modified to remove a piece of plastic to work with the adapter's centered placement of the 2.5 inch drive. FYI. Except for the above, installation was effortless. Closing the existing hard drive to the SSD using an Apricorn USB to IDE/PATA/SATA Drive Adapter was very easy. When we could boot the system we installed the Samsung utility and upgraded the firmware. Easy and no problems. The performance difference was stunning. The system booted in seconds and applications loaded almost as fast. The client was thrilled and felt it was like having a new computer at a fraction of the cost and hassle. I found the utility for the drive very useful as it could give an assessment of the drive life and helped with some performance tuning so we could get the most out of the drive. Nicely done giving the impression of a professional tool rather than an engineering afterthought. I'm giving the EVO 5 stars. It provides a great product in a great package with excellent supporting software. My only concern is one I have for all SSD drives and that is longevity. With Samsung utility addresses this issue well. Hope this helps someone! UPDATE: May 12, 2014 I recently purchased another EVO for installation in an older Dell laptop. It has only SATA II but got a great performance boost! However, some settings of the Intel SATA interface (iastor - aka Intel Matrix Storage) do not play nice with the Samsung (or a number of other SSD drives). I checked for newer drivers and the Intel driver upgrade tool said I had the latest. The symptoms are occasional hangs (maybe once or twice a day) for around a minute and log entries reporting: The device, \Device\Ide\iaStor0, did not respond within the timeout period. If you get these symptoms with your SSD and are comfortable with using the registry editor... WARNING: You can destroy your Windows installation editing the registry of your don't know what you are doing!!! That said... This issue can be addressed as follows in Windows 7: Go to the registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\iaStor\Parameters\Port0 Your port number may be different. In my laptop's Samsung EVO was connected to Port0. Next export the Port0 sub-hive (or whatever port number you are working with) to restore things in case of a mistake. Inside there you'll find 3 DWORD keys: LPM, LPMDSTATE and DIPM. All three default to a value of 1. Change all 3 to a value of 0. Then restart your computer. This worked for me and I hope this saves someone time if they run into this issue.

Excellent laptop upgrade
I've tried this on two laptops, and found it to be a very good upgrade for both. Dell Inspiron 1520. This is a 7-year old laptop with 2GB RAM. The SSD breathed a new life in it. With Windows 8 and SSD, the laptop seems to perform better than the new mainstream laptops available in market now. The drive is slimmer than the drive slot in laptop, and I had to make a spacer with paper and tape for the SSD to fit properly. Other than that, the migration process was very smooth. Dell Inspiron 15R. This is a 2-year old laptop with 8 GB RAM but an older and slow hard disk. The SSD dramatically improved the boot and login time. The effect on later responsiveness was less pronounced. I think this is because the modern OSs cache the files in otherwise unused RAM, and the disk is less of a bottleneck. Again the drive is slimmer than the drive slot in laptop, but it did not need a spacer, the screws took care of proper fitting. The migration process had a hiccup when the computer failed to boot with new drive, perhaps because I resized the partition after using the Samsung tool for migration. Luckily I had a Windows recovery USB handy and it magically fixed the issue.

Perfect for new computers and speeding up older ones
After getting introduced to the SSD hard drive I'll never go back to a SATA drive for my main drive again. The speed and reliability of this just keeps on rolling and I've never noticed to much of a slow down with the OS. I used it on an older Macbook Pro and added some more ram and it made the computer feel like new again.

Der Hammer Booster für ältere (und auch neuere) PC/MAC Systeme
Ich schreibe hier aus der Sicht eines professionellen IT-Dienstleisters mit mittlerweile mehr als 20 Jahren Erfahrung und gefühlten 2.000 reparierten, umgerüsteten, aufgerüsteten und / oder neu installierten Systemen. Ich denke das ich einen sehr guten Überblick über die Performance verschiedener Systeme, ob Server , Notebooks, normale PC Arbeitsplätze etc. habe und weiß wo diese ihre jeweiligen Stärken / Schwächen besitzen. Eines kann man ganz klar feststellen: Wenn es in der Vergangenheit Performanceprobleme bei PC/MAC basierten Systemen gab, waren diese zu 95% auf die Festplatten zurückzuführen. Oft dann noch in Verbindung mit etwas fehlendem Arbeitsspeicher. Ich versuche diese Zusammenhänge mal hier etwas laienhaft und allgemein verständlich auszudrücken. Es ist nämlich meistens grundsätzlich völlig egal ob eine SSD mal 10 oder 50 Mbytes mehr in der Sekunde schreibt oder liest (Datentransferrate), das merkt man in der realen Nutzung des Gesamtgerätes kaum. Der Unterschied ist es, überhaupt eine SSD einem System zu benutzen. Und diesen Unterschied versuche ich mal hier mal mit einfachen Worten und Zahlenbeispielen zu erklären. Dieses Review ist sehr lang, weil Vieles erklärt wird. Wer sich die Erklärungen sparen möchte und bereits warum und wann eine SSD schneller als eine Festplatte ist, springt am besten direkt ans Ende zum Fazit. Warum wird ein PC durch eine SSD signifikant schneller ? Ein herkömmliches PC/MAC System besteht im Grunde, wenn wir hier zwecks Analyse des Datentransfers und Datenverarbeitung auf die hierfür wichtigen Teile reduzieren, aus nur 3 maßgeblichen Komponenten: 1. Dem Prozessor (auch CPU genannt, das Gehirn das die Daten bearbeiten kann) 2. Dem Arbeitsspeicher (auch RAM genannt, ist quasi so etwas wie eine Kreidetafel von der die CPU Daten für ihre Datenbearbeitung ablesen kann und auch Ergebnisse aus Teilberechnungen dran schreiben kann um sie kurzfristig verfügbar zu halten) 3. Die Festplatte ( auch Harddisk genannt, ist ein Massenspeicher, auf dem endgültige Berechnungsergebnisse, aber auch weitere Massen-Daten wie Photos, Bilder, Programme etc. abgelegt sind, die die CPU gerade halt nicht braucht. Etwas zu den Geschwindigkeitsverhältnissen und den Abhängigkeiten dieser drei Komponenten: - Prozessoren sind schon seit Jahren sehr schnell und verfügen über ebenfalls eigene eingebaute Speicher ähnlich dem RAM, die jedoch verhältnismäßig klein dimensioniert sind und quasi ständig nachgefüttert werden müssen, damit weitergerechnet werden kann. Der in den Prozessoren integrierte Speicher ist vergleichsweise zum RAM Speicher und zum Festplatten Speicher sehr teuer in der Herstellung. Daher wurde dieser meist sehr klein gehalten, außer in extrem teuren Serverprozessoren (bspw. Intel XEON Serie). Zudem können die kleinen Speicher (Caches) in den Prozessoren keine Daten "behalten" wenn der PC ausgeschaltet wird. Sie dienen wirklich nur zur direkten Unterstützung des Prozessors und des direkten Rechenprozesses. - Arbeitsspeicher bietet von diesen drei Komponenten die zweit schnellste Speichermöglichkeit und hat sich im Laufe der letzten Jahre durchaus in seiner Verarbeitungsgeschwindigkeit entwickelt. Dieser dient jedoch ebenfalls nicht zur finalen Speicherung der Daten oder zur längern Aufbewahrung von Daten, da auch der Arbeitsspeicher nach dem Ausschalten des PCs "leer" ist. Seine Hauptaufgabe ist es möglichst alle Daten die der Prozessor in den nächsten Momenten brauchen könnte vorzuhalten und im richtigen Moment an selbigen auszuliefern. Im Gegenzug werden auch Daten in den Arbeitsspeicher geladen, welche vielleicht in Kürze von anderen PC Komponenten (wie Grafikkarten oder andere Hardware) eventuell kurzfristig gebraucht werden könnten. Auch größere Teilberechnungen die der Prozessor vorgenommen hat und nicht mehr in seinen eigenen kleinen Speichern zwischenablegen kann, werden im RAM temporär platziert. - Die Festplatte, ist das einzige mechanisch arbeitende Element in dieser Dreier Konstellation und auch gleichzeitig das langsamste. Hier befinden sich magnetisch beschreibbare, rotierende Scheiben in einem Gehäuse, auf welchem die gesamten Massendaten des Computers in Form von Nullen und Einsen dauerhaft untergebracht sind. Daten auf einer Festplatte bleiben somit auch beständig erhalten, wenn der PC ausgeschaltet wird. Hier befinden sich alle Daten die der PC nicht "vergessen" darf. Das Betriebssystem, Photos, Bilder, Programme etc. etc. Auf den verhältnismäßig lahmen Festplatten speichert man deswegen die großen Datenmengen, weil es "billig" ist. Es gibt kaum eine andere Speichermöglichkeit die so viel Platz zu verhältnismäßig geringen Kosten anbietet und sich eignen würde in einem PC eingesetzt zu werden. Wie spielen also diese Komponenten nun zusammen ? Hier ein typisches Beispiel, das Laden eines Programmes unter Windows : 1. Sie klicken mit ihrer Maus auf ein Programmsymbol ums selbiges zu starten. Die Verarbeitung beginnt mit dem Prozessor der ihre Klicks auswertet, weiß welches Programm Sie gestartet haben, aber selber eigentlich erst einmal nichts weiteres für Sie tun kann außer anderen Komponenten den Auftrag zu geben das entsprechende Programm zu besorgen. Dieser Aufrag landet in diesem Fall erst einmal im Arbeitsspeicher, da sich hier so einige Informationen befinden welche Teile des Windows Betriebssystems eigentlich auch noch benötigt werden um ihr gewünschtes Programm auszuführen. Wenn man Glück hat ist diese Windows Komponente aufgrund eines großen Arbeitsspeichers bereits mit geladen worden, wenn man Pech hat kommen diese Komponenten mit auf die Wunschliste zu den einzelnen Dateien des Programms die nachgeladen werden müssen. Ist die Wunschliste fertig gestellt, wird dieser quasi der Festplatte freundlich übergeben, mit der Bitte um "Anlieferung" dieser Dateien. Das können im Einzelfall schnell mal ein paar tausend Dateien sein inklusive der Windows Komponenten die da grad benötigt werden. Und da die irgendwo auf irgendwelcher der magnetischen Scheiben der Festplatte gespeichert sind, schaut die erst mal fein in ihrem eigenen Katalog nach wo das Zeug denn alles so steckt. Dann beginnen die Schreib-/Leseköpfe damit den Katalog abzuarbeiten. Da auch die gewünschten Daten meist niemals direkt "am Stück" hintereinander zu finden sind, springen die Köpfe also immer hin- und her solange bis alle Daten ausgelesen und an den Auftraggeber Arbeitsspeicher übermittelt wurden. Bis hierhin sind oft schon bereits viele Sekunden vergangen, in der Sie vor dem Rechner sitzen und sich quasi noch nichts gerührt hat. 2. Sobald die notwendigen Daten sich im Arbeitsspeicher befinden, kann der Prozessor damit beginnen diese zu bearbeiten und ihr Programm auszuführen. Die Zusammenarbeit zwischen Arbeitsspeicher und CPU ist dabei verhältnismäßig gut und zügig. Ab diesem Zeitpunkt geht also alles relativ flott und sie könnten jetzt meist schon mit ihrem gestarteten Programm arbeiten. Abgesehen natürlich von den Fällen wo sie in ihrem gestarteten Programm bspw. ein Bild laden wollen, oder eine Programmfunktion aufrufen die bis dahin noch nicht mitgeladen wurde. Dann muss die ganze Kette rückwärts mit einer neuen Wunschliste für die lahme Festplatte zurück abgearbeitet werden. Das kann dauern ' gääähn . Bei älteren PC Systemen die schon viele Jahre Windows Updates 'ertragen' mussten, und deren Hardware scheinbar nicht mehr für die heutige Zeit gebaut scheint, kann das auch schon mal der Zeitpunkt sein um einen frischen Kaffee zu holen. Das was ich hier mal bildlich dargestellt habe, würde ich gerne mal mit ein paar Vergleichszahlen erläutern um die Verhältnismäßigkeit der einzelnen Komponenten untereinander, in Bezug auf Zugriffsgeschwindigkeit und Datentransfer Geschwindigkeit zu beschreiben. Wir lernen hier gerade einen neuen Begriff zusätzlich zur bisher besprochenen 'Datentransfer' (Lese-/Schreib)-Geschwindigkeit, auch Datendurchsatz genannt: Zugriffsgeschwindigkeit Die Zugriffsgeschwindigkeit gibt an, wie lange ein Speicher braucht bis er mir die ersten von mir angeforderten Daten liefern kann, nachdem ich ihm das Kommando dazu gegeben habe. Manchmal wird die Zugrifffsgeschwindigkeit auch als 'Latenz' bezeichnet. Es ist also nicht nur wichtig wie schnell ein Speichermedium die Daten rausrücken kann wenn es einmal damit begonnen hat, sondern auch wie lange es dauert bis es beginnt zu liefern. Und hier steckt die Magie einer SSD. Hier die angesprochenen Vergleichszahlen zu den drei Komponenten in Bezug auf ihre Datentransferrate und den Zugriffszeiten: Speicher die sich in der CPU befinden: 1st lvl Cache: Datentransfergeschwindigkeit : 38 GByte/s Zugriffszeit : 1,2 ns 2nd lvl Cache: Datentransfergeschwindigkeit : 18 GByte/s Zugriffszeit : 3,8 ns Hauptspeicher (RAM): Datentransfergeschwindigkeit : 7 GByte/s Zugriffszeit : 72 ns Festplatte (HDD): Datentransfergeschwindigkeit : 90 MByte/s Zugriffszeit : 7,2 ms Technikaffine Vollprofis mögen mir verzeihen das ich mich hier an Zahlen eines Core2Duo 2,4 GHz, FSB 800, DDR2-800 Systems aus 2011 orientiert habe, welcher sicherlich nicht mehr Stand der Technik ist. Jedoch ist dieses zur Verdeutlichung des SSD Effektes völlig ausreichend und stellt die Verhältnisse immer noch sehr klar dar. Was man an den obigen Daten deutlich sehen kann, ist das die Speicher die sich in der CPU befinden (L1 und L2 Caches) sowohl vom Datentransfer als auch in der Zugriffszeit sehr schnell sind. (Die Einheit ns bei der Zugriffszeit bedeutet hier 'Nanosekunden'). Man sieht hier zwar das schon eine deutliche Diskrepanz zwischen der Geschwindigkeit des eingebauten Prozessor- Speichers (Cache) und dem Arbeitsspeicher (RAM) besteht ( Zugriffszeit 1,2ns zu 72ns, was fast den Faktor x60 bedeutet), aber es wird immerhin bei Datendurchsatz und der Zugriffsgeschwindigkeit noch mit denselben Einheiten gerechnet. (Gbyte/s = Gigabyte pro Sekunde und ns=Nanosekunden) . Eine Nanosekunde ist der ein milliardste Teil einer Sekunde, also = 0,000000001 Sekunden. Das ist fast genau die Zeit die der L1 Cache im Prozessor braucht um Daten an diesen zu liefern. Bis diese Daten aus dem Arbeitsspeicher gekommen sind dauert es immerhin schon ca. 60 mal länger (72ns). Das ist aber immer noch verdammt schnell. Und jetzt kommt das Problem : Muss ich die Daten von der Festplatte holen, muss ich mit einer Reaktionszeit selbiger von ca. 10 ms (= 10 Millisekunden) leben. Werden wir mit einer ganz anderen Einheit konfrontiert. Hier nochmal untereinander die Nanosekunde und die Millisekunde: 0,000000001 (Nansoekunde) 0,001 (Millisekunde) Eine Millisekunde ist also 1.000.000 (eine Million) mal langsamer als eine Nanosekunde. Vergleichen wir also mal die 72ns Zugriffsgeschwindigkeit des Arbeitsspeichers mit den 10ms der Festplatte, so erhalten wir einen Faktor von mal 138889 den der Arbeitsspeicher schneller ist im Zugriff auf die Daten als die Festplatte. Wenn Sie 10.000 kleine Dateien aus dem Arbeitsspeicher dem Prozessor zu Verfügung stellen müssten (gerechnet ohne die reine Übertragungszeit der Datenmengen selbst) würde das in Bezug auf eine Zugriffsverzögerung 10.000*0,000000072ns=0,00072 Sekunden dauern. Also immer noch ein 'Sekundenbruchteil'. Muss eine Festplatte wie im Beispiel diese Daten zusammenkratzen, braucht Sie alleine für das Zusammensuchen (ohne die Daten selber zu liefern) schon 10.000*10ms = 100 Sekunden. Das ist schon ein gewaltiger Unterschied und demonstriert die Verhältnissmäßigkeit in den Zugriffsgeschwindigkeiten zwischen Arbeitsspeicher und Festplatte. Das Laden von 10.000 verschiedenen Dateien von einer Festplatte ist übrigens gar nicht mal so weit hergeholt. Das entspricht bspw. dem typischen Arbeitsaufwand für eine Festplatte beim Laden ihres Betriebssystems, also wenn sie den PC oder MAC hochfahren. Und das was oben beschreiben ist, entspricht nur der Differenz in der Zugriffsgeschwindigkeit. Zudem kommt noch der Performanceunterschied in der eigentlichen Datentransferrate, also wieviel an Daten in einem bestimmten Zeitraum 'rübergeschaufelt' werden können. Hier ist der Unterschied zwischen Arbeitsspeicher zu Festplatte (7 Gbyte/s zu 90 Mbyte/s) auch noch gewaltig (ca. der Faktor 78) aber nichts im Vergleich zur Differenz der Zugriffszeiten. So und wer es durch das ganze technische Gewusel bis hierhin geschafft hat, erfährt jetzt warum eine SSD den meisten PCs und MACs einen Riesen Performance Vorsprung gibt: Ganz einfach. Wie wir oben herausgefunden haben ist eine Festplatte um ein unglaublich großen Faktor langsamer als das Arbeits-Verhältnis zwischen Arbeitsspeicher und Prozessorspeicher. Die Festplatte ist also der so genannte 'Bottleneck' (Flaschenhals) welcher immer dann wenn viele einzelne Dateien von ihr angefordert werden den Arbeitsspeicher und den Prozessor 'warten' lässt. Dieser Fall das 10.000 tausende kleiner Dateien geladen werden, kommt leider jedes Mal vor, alleine wenn Sie ihr Betriebssystem laden, also den PC einschalten. Deswegen dauert das ganze auch Minuten um Minuten. Je mehr Updates ihr PC mittlerweile für sein Betriebssystem bekommen hat, umso mehr verstreuen sich die Dateien auf der Festplatte und umso gewachsener ist die gesamte Anzahl einzelnen kleinen Dateien. Und das 'killt' über die Jahre fast immer die Gesamtperformance eines Rechners, selbst wenn der zum Kaufzeitpunkt ein 'Höllengerät' war. Sehr oft werden dann wegen solcher minutenlanger 'Booten des Betriebssystem' Orgien und einem sich teigig anfühlenden Gesamtverhalten des PCs unter seinem Betriebssystem ganze Rechnersysteme direkt ausgetauscht. Kann man machen. Muss man aber nicht. Sollte man auch nicht, vor allen Dingen wenn das neue PC System nicht über eine SSD verfügt. In diesen Fällen habe ich nämlich schon eindrucksvoll demonstrieren können das der alte mit einer SSD aufgerüstete Rechner bis zu 8 x schneller gebootet hat, als der brandneue Rechner, der aber wieder mit einer normalen (wenn auch schnelleren) Festplatte ausgerüstet war. Warum ist die SSD denn jetzt eigentlich schneller als jede Festplatte ? Weil Sie quasi fast so schnell ist wie ein Arbeitsspeicher (RAM) und keinerlei mechanische Verzögerung hat. D.h. sie ist sowohl im Datentransfer, als auch in der Zugriffsgeschwindigkeit dem normalen Arbeitsspeicher des PC/MAC sehr ähnlich, und kann damit tausendmal effizienter im Team und im Zusammenspiel von Arbeitsspeicher und Prozessor mitwirken. Eine SSD ist ein so genannter 'Flash' Speicher, was bedeutet das sie ihre Daten nicht wie ein normaler Arbeitsspeicher beim ausschalten des Computers 'verliert'. Somit eignet Sie sich auch erstmals zum Ersatz einer Festplatte die ihre Daten ja magnetisch (relativ) dauerhaft speichert. Ein simples Rechenbeispiel: Das weiter oben genannte PC System soll 'gebootet' werden. Das typische Windows besteht aus 2 Gigabyte an Dateien die in den Arbeitsspeicher geladen werden müssen und ca. 10.000 einzelnen Dateien. Für das obige PC System das die Daten von seiner Festplatte laden muss bedeutet dies: Für die reine Zugriffszeit zum Laden der Dateien: 10.000*10ms = 100 Sekunden. Zzgl. der Zeit zum Übertragen der Daten selbst, 2GB / 90Mbyte/s = ca. 22 Sekunden. Also in Summe ca. 122 Sekunden. Mit rund zwei Minuten ein typischer Bootvorgang. Rüsten wir das System jetzt auf eine SSD um, sieht die Rechnung ca. aus wie folgt : (Wir kalkulieren mit einer marktüblichen SSD mit Zugriffszeiten um die 0,1 ms und einer Datentransferrate von ca. 500 Mbyte/s. Der Fairheit halber (ältere PC Systeme können diese hohen Datenraten oft über ihren älteren internen BUS gar nicht abbilden, rechnen wir hier mit 30%,also mit 150 Mbyte/s )). Für die reine Zugriffszeit zum Laden der Dateien: 10.000*0,1ms = 1 Sekunde !!! Zzgl. der Zeit zum Übertragen der Daten selbst, 2GB / 150Mbyte/s = ca. 13 Sekunden. Also in Summe ca. 14 Sekunden. Das entspricht einem typischen Bootvorgang eines Betriebssystems mit SSD. Man erkennt hier deutlich das mit einer SSD das Hauptproblem, nämlich die Zugriffszeiten auf die vielen tausenden Einzeldateien durch den Einsatz einer SSD fast komplett eliminiert wurden. Wer das jetzt bis hierhin verstanden hat, weiß wo die Magie einer SSD liegt, was diese vermag zu leisten, und das es eigentlich fast schnuppe ist, welche Datentransferrate eine SSD letztendlich bietet. Für eine höhere Datentransferrate einer SSD viel Geld auszugeben lohnt sich maximal für ganz neue, hoch performante PCs / MACs mit den entsprechenden Bus Systemen, die diese Daten auch weitertransportieren können. FAZIT: Für ältere PCs sind die SAMSUNG Festplatten mit ihren in Relation zur Konkurrenz gesehenen, mittleren Datentransferraten und ihrem günstigen Preis völlig ausreichend. Zudem verfügen die Samsung SSD standardmäßig über eine mitgelieferte Software, mit deren Hilfe man das Originalbetriebssystem meist bequem von der alten Festplatte auf die SSD übertragen kann. Zudem sind SSDs durch die nicht vorhandene Mechanik im Gegensatz zu Festplatten völlig resistent gegen Schocks (gerade wichtig für den Notebookbetrieb unterwegs) und verbrauchen aus dem selben Grunde auch deutlich weniger Strom. Es gibt viele gute SSDs auf dem Markt von verschiedensten Herstellern, aber in Bezug auf Qualität, Performance, Lieferumfang und Preis-/Leistungsverhältnis kann ich aus vielen Jahren Erfahrung die SAMSUNG SSDs nur empfehlen. Ich habe insgesamt mittlerweile ca. 70-80 SSDs (meist SAMSUNG SSDs aus der EVO Serie) verbaut und hatte mit den SAMSUNGSs niemals Probleme oder Ausfälle. Ich hoffe das ich mit diesem etwas ausschweifenden Review einigen Leuten nahe bringen konnte was überhaupt genau der Vorteil einer SSD ist und wie dieser zu werten ist. Sollte diese Rezension für Sie in irgendeiner Form hilfreich gewesen sein, so klicken sie bitte unten bei "War diese Rezension für Sie hilfreich ?" auf JA. Nur so kann ich beurteilen ob meine Form von Produktbewertung anderen Menschen hilft oder nicht.

Works perfectly with Dell Studio 1555
The disk is obviously a direct fir and post installation the laptop is giving pretty good response and boot up time is very less as compared to my old disk. There are many software products to clone your old disk into this new disk to use, but i personally recommend starting from scratch and installing fresh operating system directly to the new disk using your windows recovery disk or linux cd. You can use a caddy and use the old hard disk as an external hard disk or swap temporarily in case you forgot something in your old installation. Hope this helps others in choosing this product. Highly recommended as its much cheaper than the pro version but quite reliable for home use.
