VANTEC 4-Port SUPERSPEED USB 3.0 PCIE Host Card W/Internal 20-PIN Connector

Worked as intended! Easy installation just plug and play.

If you need PCIe add-on USB cards, you can't go past Vantec. I'm an IT professional, I've used pretty much every USB add-on card with a decent brand name on it (and plenty without) - the Vantec cards are hands down the most reliable. I've had USB ports stop responding, burn out, crash the whole OS whenever anything is plugged into them. Mostly, I've seen ports incapable of sustaining the speed they are certified for. If the USB architecture built into Intel chipsets is the gold standard, then Vantec cards get the silver award, and no other brand even rates (because Marvell don't produce add-on cards directly, so manufacturer brand can cause Marvell product quality to vary wildly). Vantec cards provide the highest performance I've seen from non-Intel solutions, with the most stable and reliable operation. I've seen front panel ports that couldn't power a USB3.0 HDD, but they've never failed, burnt out or crashed the OS - they simply don't present the drive to the OS. I've *never* had a Vantec card fail to present a drive connected to a rear panel port. So if I need to add USB ports to a PC, workstation or even server, I insist on Vantec. I even have to import them most of the time, because there is very little local supply. I can say with great confidence that Vantec should be on the top of your shortlist, and even if it was the only brand you even considered, you wouldn't go wrong - that's where I'm at, after spending hundreds of dollars over the last twenty years evaluating various alternative products. Highly recommended.

I added this to a ryzen system to have more stable USB for an audio interface without other USB devices causing issues. So far this seems to have worked great, HOWEVER, I found that I had to avoid installing the drivers and use the default Windows drivers instead. Otherwise some devices wouldn't function correctly. The drivers are really only for Windows 7 and below.

I bought this for a PC build when the case came with more USB 3.0 ports than my motherboard had room to accommodate with the standard 20-pin cable. So I bought this to ensure USB 3.0 speed and reliability at both the front and rear of the case. It was very simple to insert into the PCIe slot and to connect the power and 20-pin cable feeding my 2 front slots. It came with a link to drivers, but the slots worked without any issue on both Windows 10 and Ubuntu 18.04 LTS. The transfer speeds when I copy video or pictures from phone to PC is noticeably faster than on my USB 2.0 ports. My only complaint is that my phone won't rapid-charge on any of the USB 3.0 ports, even with the OEM charger cable. Real first world problems.

Installed card in 5 year old PC (first gen i5) running Windows 8.1. Works great. Transferred 2+TB of data from external HD to internal HD (SATA 2 connection) with no problem. Supports UASP which increases transfer rate if also supported by external drive. UASP is not mentioned in documentation, but confirmed with e-mail to Vantec support and by use after installation. Note: Definitely install drivers included with card. I ran into issues using native Windows 8.1 drivers, where data transfer would pause for ~30 seconds every two or three minutes. Acted like a buffering issue. I installed included drivers and issue disappeared, so I didn't troubleshoot further. Note: The card is PCIe x1, so you won't get the full 5 Gbps of USB3. That said, PCIe x1 is faster than a hard drive, so this won't be an issue when using external drives. If you do need the full USB3 speed (for SSDs, multiple simultaneous HDs, etc) then look at Vantec's PCIe x4 board. This is a solid board that works great. I would have no issue buying another if the need arises.

It works great, not as fast as the on-board 3.0 ports but it is still better than USB 2 by a long shot. Its great to have 4 more ports that are not supported by a hub. I would buy again if I needed to add more 3.0 ports.

The card (UGT-PC345) is an older USB-3.0 adapter and is being sold under the brand Vantec. I've used Vantec case fans in the past and wanted to try this product out to get USB-3.0 on my system. For the most part it works. However it seems to be having a strange effect on my M4A78T-E motherboards power management. Sometimes it comes out of sleep mode as is if it was hibernating. It never did that before. At least one time the bios crashed during the wake up process. I tried finding an updated driver but both the hardware and driver date back to 2012 with no updates since. Norton file in-site lists Renesas Electronics Corporation as the origin of the driver file. I did use it with external storage device and it worked well. It is not clear whether this card is compatible with Windows 10 or not. Driver was not available for download from Microsoft for windows 7. Used the version on included CD.

This review is for the Vantec 4 Port USB 3.0 PCIe with Internal 20 pin Host Card (UGT-PC345). I wanted to add USB 3 ports to my old Dell Inspiron 580, running Fedora 31 Linux. This couldn't have been easier. I installed the card into an open PCIe x1 slot and connected an available SATA power cable to the molex adapter (included). Linux recognized the USB ports right away. I get about 145MB/s writes to a SanDisk Extreme flash stick where I used to get about 24MB/s on 2.0. Oh and I bought this too to run 2 ports out the front: https://www.amazon.com/gp/product/B01C1KW5L8/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 That worked like a charm too. It fit where the old multi-card reader was on the Inspiron 580. Also thumbs-up to Vantec tech support: I emailed them before I ordered since there was conflicting info about PCIe x1 vs x4 in these reviews. Within minutes they confirmed that this is an x1 card and also that there should be no problem on Linux.

Compré esta tarjeta ya que actualice mi ordenador y no tomé en cuenta que la tarjeta madre no incluye conector USB 3.0 de 20 pines para los puertos frontales de mi gabinete, al instalarla de manera automática la reconoció el sistema operativo, funcionan muy bien tanto los puertos de la tarjeta como los frontales y ofrecen una gran velocidad de transferencia.

Items arrived very well packed and in perfect condition. I upgraded an old Biostar AM2+ motherboard with those. I am pleased how the final configuration turned out.

Used to provide USB 3.0 capability on Dell Inspiron 580 running Linux Mint 18.3 Plugged into PCIe slot and connected to SCSI power via supplied adapter cable. The card and USB ports were active on reboot and recognised correctly as USB 3.0 without having to do anything else. I ran a number of benchmarks to connected external 2TB Toshiba drive using rsync. The write speed on the card was about 4-5 times faster than on the USB 2.0 ports on the PC.

I have a FreeNAS running on a ASRock 2750D4I in a Fractal Design node304 case. The 2750d4i does not have USB3 headers for the Fractal Design's USB3 ports in the front of the case. This card was essentially plug/play. It was recognized in FreeNAS 9.10 (freebsd 10.3) with zero configuration. The motherboard recognized the card immediately. I was able to boot off of it using a USB thumb drive to install FreeNAS on an SSD. Excellent card for very good price. If you need USB3 for FreeNAS/FreeBSD get this card! I haven't run a USB3 drive off of it long term. Will report back and update if I run into any problems. == Update Dec 1/2017 == I plugged a 8TB Seagate Backup Plus Hub (STEL8000100) into the USB ports on the card. FreeNAS immediately recognized the drive and I was able to format and add it as a new volume from the web interface. I ran an rsync of about 3TB of data and it seemed to be able to maintain 100MB/sec for most files. Since it was transferring a lot of small files (photos/short video clips) it was limited to the drives latency. Considering everything was plug/play with FreeBSD/FreeNAS I 100% recommend this card! Here are some basic drive benchmarks which shows the drive at about 160MB/sec. Not bad for a large slow disk over USB3.

Bought for the front panel connector on the card. Still using an old 1st gen i7 that did not have USB3 but the case did. USB speeds are great now, detected immediately. ports can even be used in bios surprisingly, seems it just uses legacy drivers as well. Great card if you do not have USB3 or the front panel connectors on your motherboard.
