KOMPUTERBAY 32GB Professional Compact Flash Card CF 1000X 150MB/s Extreme Speed UDMA 7 RAW 32 GB

I purchased this Oct 3, 2013 for my Canon 5D Mark iii and received it in 2 days. I purchased this card only because my SanDisk 32GB CF card gave up on me resulting in a loss of 3 hours of shooting. I wasn't able to benchmark this on my computer due to the lack of a CF card reader on this trip, but I was more concerned about performance while taking pictures.Using the Canon 24-105mm lens and a half-charged OEM battery, I held the shutter button down while focused on my iPads timer to see how many seconds it would last without "buffering" and was able to take 170 pictures in 30 seconds and decided to give up since I didn't hear or notice any performance change in "buffering" - In other words, it didn't buffer after 170 pictures in 30 seconds so I decided there was no need to continue. You can judge the "buffering" performance yourself as it can be measured in other ways with different camera settings. I may retest when I have the time.During my 6 weeks of ownership, I have taken 9,812 pictures on this card with zero loss or transfer problems. It has been through TSA's X-Ray machines 15 times with no ill effects.I guess you also can't go wrong given the Lifetime warranty... err, unless you lose pictures like my $150 SanDisk CF card did.....

I have been using this card for a couple of months. This card performs really well in my Canon 5D III. I use it mainly for photos and very occasionally compressed videos. The 32GB size can hold over 1,000 raw files from my 5DIII. What really impresses me is the the speed. I could fire about 70 continuous shots in high speed mode (6 frame/s of 22MP full size raw files) before it slows down. In comparison, my SDHC card can only handle 15 high speed shots (which is mostly due to the camera buffer). I haven't done any benchmark testing of the speed, but 70 shots at 6 fps is more than enough for me. I wanted a fast card but didn't want to pay too much for cards from more well-known brands, as I don't make a living with my photography. This card hasn't disappointed me.I have heard of people having trouble with this (or the 64GB version) card after formatting it, primarily in order to hold single huge-size raw video. So I tried to avoid formatting it, either in camera or with a card reader. Deleting the contents with a computer or erasing in camera works really well for me so far. The card has been rock solid so far, and I expect it to last for years.Considering the price and the performance of this card, I would highly recommend it to anyone.

I am a documentary filmmaker and professional freelance photographer. I need a lot of memory to store video footage and RAW image files, but don't have the budget to go with a name brand. After reading the reviews, I bought 3, just in case there was a malfunction, I'd have a back up. I have been using the 3 cards quite seriously in winter outdoor weather conditions (so far) shooting on a 5diii both RAW and large video and the cards have performed beyond my expectations. I have had no problems or malfunctions and have filled all three up several times over during a month of video and photography work. There seemed to be a reoccurring problem in the comments with formatting, I have an older Delkin Devices card reader, which I have used for all photo/video transfers, and have had no problems with the Komputer Bay flashcards. I always reformat my cards in camera as well-and have had no malfunctions there either. I think many people reformat cards in their card reader, which can cause problems in general. Great value for me so far, I will probably purchase more of these cards in the future, I would like to push their longevity, but I'm already hopeful that this is a great deal and seems to be a great product!

I was concerned about ordering a Computer Bay product as all my previous cards have been SanDisk Extreme. The only two problems I've had with the SanDisk are that they feel slow to load and that they are relatively expensive. I say relatively because the speed is relative to photo handing once it is loaded onto the computer. In any event, when I was looking for a larger card (my wife took 5 cards on holiday and was put out one day because the card she had with her was full) and decided to try Computer Bay. I haven't benchmarked the card but am pleased with the speed of the reading. I can't give all the credit to the card because at the same time I added a USB 3.0 card and 3.0 reader to my system, so over all improvements cannot just be attributed to the card. So far the card has preformed as expected.

I received my card very quickly - shipped fast! I thought it was a good value for the money.I installed it in my camera and it worked correctly right away. When I went to download my pictures the card was not recognized and every attempt I made the computer or camera wanted to format the card. Of course this happened with my vacation photos on the card. I ended up ordering a new card reader at the advice of tech support, did not work, card still wanted to be formatted.I ended up paying to get a program to save my pictures. So in the end I did not save money over a different brand of card.Once formatted I am sure the card will work correctly. So if you purchase, format your card right away and I am sure you won't have the issue that I did. Also - make sure you have the correct card reader or it will corrupt the card.
