When I was shooting with cameras of 40D and earlier vintage, I never noriced any difference in CF card speeds. However, when I switched to a 7D with larger files and UDMA capability, the Lexar 300X and 400X speed cards performed faster (the red write light was on for a shorter time).

I am sure that Sandisk and Transcend CF cards of similar speeds would perform equally as well.

NOTE: Although my 40D camera doesn't take advantage of UDMA write capability, the CF card with UDMA and using a UDMA capable card reader will transfer files at a noticeably higher rate. This helped during my two week trip to China when I needed to transfer more than a thousand exposures each day. I was shooting in AEB since this was my only trip to China and AEB is a security blanket...

Even the "X" speed isn't an absolute measure of performance. For example, the Delkin 1000X card has the same 150MB/s read speed the 1000X Lexar Professional card does, but only 50BM/s write speed vs. Lexar's 95MB/s.

If you don't shoot long and repeated bursts, the only consideration, in terms of speed, is transferring to your computer.

I also use Transcend and have for about 5 years without a hiccup. 16 gig cards on a 5DII...you'll get about 580 images. I really do not see the need for larger cards... the again I do not know what/how you shoot.

It really doesn't matter HOW fast they read. Most of the hard drives I work with will generally transfer at about 90MB/sec in a burst and 60 or so sustained. SSD will go maybe 120.....

It can/does matter. I do not think there are readers, yet, that can pull data off of CF cards that fast so the limitations are the cards and the readers.
