Hello, between the Sandisk Extreme 60 MB/s and the Sandisk Extreme Pro 90 MB/s on a Canon 7D would I notice much difference? Can the 7D take full advantage of 90 MB/s?
Thanks for the help!

This is a pretty popular test comparison test site:

Also remember if you use a quality CF card reader and even moreso if it's USB 3.0 then you can take full advantage of the read speed to get the images onto your computer. When you get into 16, 32, 64 and 138 GB cards that extra speed can add up into meaningful time.

Ditto, they've replaced my Sandisk and Lexar cards over time really like this card for speed, capacity and value for money

+1 for the 32gb Transcend 400X. Maxell 16gb 400X from B&H also a bargain. Put your money on something other than overpriced SanDisk.

I've had 2 out of 3 Transcend 400x 32GB cards fail over the past year. When the first one failed, Transcend replaced it, and that one is going fine. This past week I've noticed that the transfer time of images from my second card to my Macbook Pro (using a USB3 card reader) had slowed to a crawl, and using Blackmagic Disp Speed Test app, I can verify that read performance on this chip is very poor. I'm going to replace it with a SanDisk card and stay away from the cheap Transcend CF cards from now on.

Unless you plan to shoot a lot of video.

Why? Video is remarkably undemanding. The manual says that 8 MB/s is the speed required. So there will be zero difference between a 60 MB/s or a 90 MB/s card.

I personally use SanDisk Extreme 60 MB/s 16GB cards exclusively now. The camera itself really won't benefit much from faster cards as you are still limited to write speeds of the cards, not the read speed. As previously mentioned by other users above, the only benefit to going with faster cards are to transfer files off the cards to some other storage medium. Here again, unless you have a fairly new computer with USB 3.0, you will be limited in read speeds as well.

Also, this is just some food for thought based on my previous experiences. If I had the choice between two 16GB cards and one 32GB, I would choose the two 16GB cards as in the event one of my CF cards go bad, I don't loose everything. You need to ask yourself if risk in convenience of not needing to carry multiple cards around out weighs the risk in losing all your work if that one card goes bad. The other reason I have switched from Transcend cards to SanDisk was reliability. I experienced 3 card failures in one year with Transcend and although Transcend was good about replacing the cards, its harder to replace the work you lost. I am not saying SanDisk cards won't go bad, just so far in my experience I have not had one go bad as of yet and I also do not put all my eggs in one basket, which is why I use multiple smaller cards. Keep in mind I have not done much with video, all my experience is mainly shooting RAW photos. I tend to swap cards every 300-350 frames instead of filling the cards to max capacity and formatting the cards after transferring to the computer and a backup drive.

I have used all SanDisk Extreme cards for years now and have had little problems if any. Very Happy!

SanDisk Extreme IV is the only card ever to fail on me in 8 years of digital shooting and I have a lot of CF cards. Prior to the failure I was a SanDisk only user too. Any card can fail, but expectations are higher when paying a premium price.
