Ken, are you familiar with the CF card testing done by Rob Galbraith? Here's the link to his tests for the 1dMkII:
http://www.robgalbraith.com/bins/multi_page.asp?cid=6007-6896 I've heard (but not tested) that 4Gb cards are inherently slower than 2Gb cards, perhaps due to cluster sizes or other factors.

Any idea how fast this card would be with a 1D Mk2? I currently have a 4GB Sandisk Extreme III CF card bought a year ago with this camera, and it is noticeably slower in write speed than the Lexar Professional 1 GB CF cards I bought 3 years ago, I would estimate at maybe 30% slower. This is generally not a problem as the buffer memory in the camera is large enough to allow me to continue shooting in the large .jpg mode, but I have to be careful in the RAW+L.jpg mode as I can easily overflow the buffer and the camera will not allow me to shoot more images until the buffer is partially cleared. Thanks for any info.
