Good but not great for the Canon 7D,
This review is from: SanDisk 16GB 60MB/s Extreme Compact Flash Memory Card - Frustration Free Packaging (Accessory)Bought this for my new Canon 7D at Christmas. Initially quite pleased as it will record HD video options straight to the card without stopping because the buffer is filled. However what it can't do is record the 8 frames per second either in RAW or MRAW or the highest 18MP JPEG format for very many shots before it fills the cameras buffer and slows down(a lot).
I tested it and even when the medium sized files of 10MP are selected it can shoot just under 30 shots continious(2 and a bit seconds with your finger held down is not a lot of action captured) before the camera slows down.
I think I should have saved up for the next card up in the series (at time of writing it costs double this card)- the PRO version or the top of the range lexar card.
You could ask yourself when you might want to shoot 100 frames without pausing but it would be nice to be able to keep up with the camera having got this lightening fast machine.
In summary a card that will keep you happy . . . .for a while but if you have the money buy the more expensive one as this has limitations when used with the 18MP Canon 7D.

The write speed of the 7D is about 2 frames per second after a couple of seconds once the buffer is full, it's not read speed of the card that is important, it is the write speed of the camera and card that is important. There are no Compact flash cards anywhere that could record 8 frames per second of 7D sized RAW files, what size are they, I would guess a bit over 18MB each.
Modern flash cards are fast but they are nowhere near as fast as the volatile RAM that is your camera's buffer.
The high speeds quoted on these cards relate to the speed you can read from them once they are connected to a PC, a fast card like yours should be great at transferring files to your PC but no current card is going to give you non stop recording of RAW at full camera frame rate, it's just not going to happen. The very best Lexar 600X card might give you 58 frames of RAW + Jpeg in 30 seconds, you are looking for 480 frames in 60 seconds if you expect non stop recording, not possible sir!
Lastly the card does not fill the camera buffer the card empties the camera buffer, the camera is what fills the camera buffer. The card does not slow down, the camera's ability to write to the card is the limiting factor.
I have been considering this card for an older 1D Series camera but likely will not get it as it would be overkill for the above reasons.

A very helpful and instructive comment. Been thinking about additional cards for my 7D and this was really useful info, especially as regards use with RAW settings. Thanks Jim

Thanks a lot for that coment i was about to get that card as well and after couple of test with friends cards setled on way cheaper 30 mbs card that unless trigger happy does the job nicely enough. Maybe if one is in the sports photography or wildlife indeed one needs 100+ mb/s card write speeds .
