Transcend 32GB CompactFlash Memory Card 400x (TS32GCF400)

I generally avoid these sorts of super sized memory cards because I don't like having all your eggs in one basket should the card fail, get lost, etc. and you could potentially be out a huge number of pictures vs spreading them out over smaller cards.But, for certain kinds of shooting, it sure is nice to be able to just click away and not have to worry about changing cards midstream.So, I bought this little gem and I'm quite happy with it. It has proven to be a fast and reliable card so far with no issues noted.Works perfectly in my Nikon D700 and the camera reports it can fit 896 pictures on a freshly formatted card in RAW+max quality JPEG mode although I wouldn't be surprised if the actual number is closer to 1K as Nikon's tend to be conservative in reporting the number of shots that will fit on the card and revise that number as you shoot. But I wouldn't know as I haven't come even close to filling it up yet before all the pictures get transferred off at the end of the day. At the lowest JPEG setting, it reports a laugh inducing 41K images that can fit.UPDATE: I've since moved to a D800 and this is the perfect card for this camera. With its 36MP of awesomeness, it no longer seems like the enormous card it once was, but it's just about the perfect size to take a decent number of images with without having to swap out cards too often. Holds somewhere in the neighborhood of 400 RAW images at max settings with 14 bit mode and lossless compression enabled. Plenty fast and works perfectly.

I have had this card in my 7D since I bought them together and never had a problem with it.I am not a videographer but I did try video with it recently specifically for the purpose of testing the card speed - no problem at all, it does not even display the bar graph on the buffer being drained as the video gets recorded.I shot nearly 30K pictures with it now, plus maybe half an hour combined movies and the card had no problem.I read a number of remarks on this card and its bigger (albeit younger) sister the 64MB version and people complain of how the card stops working after some time, is not recognized by the camera (whatever camera) or the computer etc.There can be any number of reasons for that but let me start by saying that I live in the very humid Costa Rica, I have been taking a lot pictures (>250k) with numerous digital cameras since 2000 and I never, ever had a card failure, be it SD or CF.I am a design engineer who has worked in maintenance years ago.One classic point of failure is connectors.The CF cards have a 50 points female connector with very small holes that need to remain clean and dry to ensure proper operation. The more you move your card around the more chances it has to get dust or moisture in there that you will not be able to remove.People will point out that the contacts should not oxydize thanks to their coating, maybe, but moisture will change the capacitance of the contact and it may not be even between lines of the same bus, leading to timing differences between pins - the faster the card access, the more problems you will get.And don't try to use a cotton-tipped swab to clean the CF card slot in your camera: you will bend the male pins which are small enough to fit in the corresponding female holes.The mini-USB B connector, on the other hand, has only 4 contacts than can be cleaned reasonably easily, and a faulty cable can be replaced at nearly no cost - you certainly have spares around. Some will point out that the USB is slower than direct CF access - it is frequently true depending on the camera model, the computer and the cable, but in my book reliability comes way before speed and the difference is not that bad anyway, especially with the 7D.Another issue is how the CF card gets mounted by the OS on the computer.The CF card is like a hard drive or a floppy (for those who remember these guys) in that it relies on specific sectors telling the computer or camera where to find what file. The way these sectors are coded was originally defined for small volumes and then modified over and over as new features were added: hierarchical folders, long file names, more than 720kB for the whole disk etc.Why do I mention that? Simply because the format of these sectors has grown exponentially complex and confuse and differed between the computer manufacturers (e.g. the same physical floppies could contain 720k on PC and 800k on Mac) and therefore it became difficult to be compatible with everyone.The 64GB CF is nearly one million times bigger than the original floppies.Bottom line: it is safer to use one and only one computer to access the card: this computer should be your camera. Chances are its interpretation of the CF card format will be consistent and it does not need to be compatible with either PC or Mac.Any different OS, any actual card reader you use, with any different driver can be a cause of incompatibility.The more you use your camera's extended capability to store pictures or movies in subfolders, to lock them against accidental deletion etc., and the more you do the same with the computer, the higher the chances you will find a misunderstanding between the card reader / driver / OS you use and the camera on what is meant by what in the CF card formatting.Hey even computer internal hard drives get corrupted somtimes.Just don't take that chance.When you retrieve your pictures, just get them all and sort them with the computer, then "delete all pictures from card" to avoid fragmentation.When I have had to remove a card and connect it to a computer, I always reformat it right away with the camera. This way even if the file system was corrupted due to anything (not pointing fingers here) it gets back to a known, clean state.My point is I need my camera to be able to take pictures; I don't need it to store them or to backup Word files as I have seen some people doing.A card this size allows me to shoot sports for hours (e.g. yesterday at a kids swimming tournament, 3200 pictures) and I hardly pass half the card size in JPEG best def. including two test movies. Then I don't need to swap cards at all.Some pros and books advise to always have backup cards because card failures happen. They will call me a heretic for this advice but maybe if they did not swap cards they would not have failures in the first place.At some point before really big cards exist it made sense to have a few.Not anymore.

The media could not be loaded. This product Transcend 32 GB Compact Flash Card 400X (Blue) is great deal for the money. Be sure to order far enough in advance to get your, and NOT because of Amazon's shipping but because I had ordered 4 of these for a wedding and 3 of the 4 were bad. NOT the same deal with these. I am headed to Europe on Sunday and these were such a good price I had to try them again. They arrived in good enough time... although we had hurricane Isaac down here, Amazon kept me informed that they were on their way but due to delay in the weather. They texted me when they arrived, I got them quickly loaded them into my camera and fired out 15-20 test shots on each card... ran 30 seconds of video recording to each card and it all went smoothly. I have to say that I think some of the blacks that are processed on this card are not as good as they could be.... so perhaps dont shoot in dark situations.... but use cards in bright light.... but again with the right price I can take some things into consideration. These were a good buy and are performing well! Ill update this review after I have burned thousands of shots with them! I will say that I have bought the Duracell 32gb compact flash cards and they have have held up in the harshest conditions... while volunteering in Africa so I am super duper please with those.... if you wanna see those... here is that link.... Duracell High Speed 32 GB 600X USB 2.0 Compact Flash Card Card UDMA DU-CF6032G-CBack to the Transcend cards...I really think you cant go wrong with the Transcend ones. I have bettered my opinion of them with this second go around of cards.. .also consider ordering them far in advance so you can check them out and return them if needed and get another set before your shoot.Excellent deal, worth the money, lots of space for hd filming! and at 400x this aint bad!
