SanDisk Extreme CompactFlash 64 GB Memory Card 60MB/s SDCFX-064G-X46

Customer Reviews:* I'm using this CF card with my Canon 40D. Previously I was using 4gb Lexar 300x cards, (equivalent to about 45mb/sec) which also work just fine, but they're only 4gb each. I found myself wanting more memory and a 3rd card to go between my two camera bodies (other is a rebel xti).There's nothing at all wrong with this CF card, it works just perfectly. Not even a hiccup. So that's good.I was hoping to be able to take much longer continuous sequences of photos on the 40D at 6.5 frames/sec. With the Lexar 300x cards I was able to get 15 consecutive images at full resolution raw+jpg before the camera's image buffer filled up. With this card I was disappointed to find that number only rose to 17. I later looked up the stats on the 40D and found that 17 consecutive full res images was the maximum the camera can do anyway, so I know the card is faster than the camera. If I was to get a faster card it wouldn't help me at all.So, unless you really need to take lots of fast sequences at full resolution raw+jpeg, save yourself the money and get a slower 8gb CF card, like the 15mb/sec 8gb card for $30.I'm happy with the card though. It won't be holding me back. * The Sandisk 16GB Extreme card is excellent.I remember when 16Gb cards first came out, they were way expensive, and I thought "I just don't need that big of cards." Since then the price has become cheaper, I have become more of a lead finger, my cameras have more pixels, so there is no reason not to have a bigger card.I used this card on a recent photo shoot and found that I did not fill the buffer as much as I normally do. I thought that the camera write speed was matched by normal cards, the Extreme cards can write faster, making less missed opportunities.If you shoot in RAW format your file sizes are larger, and with cameras out now that record 70mb files, you will need to have faster cards, and a lot more storage. So get the Sandisk Extreme, they are at a good price.
