For video work, on either the 5DMarkII or 7D, would you think the Sandisk Ultra Compact II (30mbits per sec) would be good enough?
 
The Canon cameras need 50 megabits per second, which is about 6 megabytes per second. Make sure you know the difference between megabits and megabytes. (It's a factor of 8.)
 
I know from experience the sandisk II cards aren't fast enough on the 5D II. You can get away with a little less write speed if you are shooting 24P, audio disabled and a low ISO but I still wouldn't think you could get away with those cards.
 
Almost all CF cards on the market are faster than the suggested 8mb/sec Canon suggests.I have been buying kingston cards. One went thru the washer and dryer! with no problems. Clients data was still on it, thank god.
