The Price of Megapixels and High Cycle Rates,
Verified Purchase(What's this?)
This review is from: SanDisk 32GB Extreme Pro CF memory card - UDMA 90MB/s 600x (SDCFXP-032G-A91, US Retail Package) (Personal Computers)
Previously on Amazon, I have favorably reviewed CF cards at successively higher standards of capacity and write performance. This is my current champion. It is expensive but enables me to keep a 5D Mk2 pumping out RAWs without the camera stalling while waiting for the buffer to clear. Slower cards (133x, 300x) will stop the camera, but I've never been halted when using one of these 600x cards. A smaller version (e.g. 16GB) would have the same virtue at a lower price, but with RAWs on the order of 25MB apiece, one has to have speed and capacity in the same card. (I did previously buy one of the 16GB versions of this card as a "low-cost experiment," and it's fine for shorter jobs.)
I give four stars instead of five because of a fluky issue with sometimes (only sometimes) having the card not recognized at first when connected to a computer for download. This has happened with two of these cards using two different Firewire readers on three different machines running two different operating systems, and it hasn't happened with the 16GB version or with any other cards, so I think it's a card thing, not a "me" thing. It always works after a few disconnect-reconnect tries, but it does make a fellow nervous. A bit of a mystery, but not one to make me use slower, smaller cards.

Is it possible it is your card reader not being recognized? I have had the same issue with other cards. I have used my 32 GB for about 3 years now and it accepts images as fast as the shutter shoots. Currently using the 7D at 8 FPS.
