-Canon 5D Mark III with battery grip – 2 fully charged batteries (grip doesn’t matter)
-Freshly in-camera formatted CF cards
-ISO 100, 1/8000s, body cap (so f/0, manual focus)
-ALO, High ISO NR, vignette removal, CA correction OFF
-High Speed Drive
Note: I realize that the body cap photos are all black and real photos will be larger and slow the camera more, but I think that this is the only way to have a 100% reproducible test.
-Depress shutter fully until the camera slows
-Wait for buffer write to finish
-Press image review – look at # of images, subtracting the extra frame that indicated the buffer was full
-Sandisk 16GB (SDCFX-016G-A61) UDMA 60MB/s read/write speed rated: 19 frames
-Lexar 32GB 1000x (LCF32GCTBNA1) UDMA7 – 150MB/s read / 95MB/s write speed rated: 23 frames
-Sandisk 32GB Extreme Pro (SDCFXP-032G-X46) UDMA6, 90MB/s write speed rated: 25 frames
-Sandisk 64GB Extreme Pro (SDCFXPS-064G-X46) 160MB/s read / 150MB/s write speed rated: 35 frames
The new card isn’t quite a 50% boost over the previous generation, but it’s close, and being able shoot at 6fp for at least 5 seconds straight in a 5DIII is excellent. I’m sure the 1DX, D4, and other cameras would also benefit from the card.

— What happened: card corruption in the middle of a performance gig
I bought this for a large performance job where i would need to shoot RAW rapidly in low light conditions. sadly, during the first night I used this card, it became corrupted–likely due to an overwriting error that i didn’t have much control over. the camera would not turn on or respond if the card was inserted in the body, and mind you this happened in the middle of the performance so i was freaking out on all the missing photos. luckily, i had two camera bodies and extra cards prepared, but none of them had the same writing speed so it was less than ideal.
For anyone shooting performances/weddings/events, I highly recommend reading up on what to do when this happens. I was in such a state of panic since I’m still relatively novice and didn’t expect this to arise.
— Failed attempts to recover / reformat
The purchase comes with SanDisk’s card recovery program called RescuePro Deluxe, which is an ok software but I didn’t have any luck recovering my photos. I tried some others as well with no success, so the next step became to figure out how to reformat the card. I followed instructions from Sandisk on how to use Disk Utility in Mac to recover, but the operation failed. I tried again with RescuePro Deluxe, as well as a 3rd party disk mgmt software I use for my hard drive. None of these were successful and I believe the card’s partitions got messed up. After requesting product support, SanDisk told me to just request a replacement or return as it is probably not worth it to repair the card at this point.
It’s a little disappointing that this expensive card didn’t deliver what I wanted, but I recognize that these things can happen and now I know about precautions to take when I buy my next card. I still give this product 3 stars because SanDisk’s customer support responded quickly and helpfully.
– Use smaller cards in case one fails unless you really need all of that memory in one go (more likely for videos)
– Read up on card recovery before shooting events and take measures to prevent it
– Always have backup cards and cameras — sometimes the camera can cause the issue and if you’re on the go it might not always be possible to stop and troubleshoot
