I think we need to be carefull when comparing these cards and take the advertised speeds with a grain of salt. Although the 5d2 isn\'t listed yet, you can use other new cameras that may be similar in performance.
You also have to pick the proper camera for a comparison. for example, the 1Ds mkIII doesn\'t support UDMA, so the fastest cards won\'t perform the best with it. Also, its older processor, the Digix III, is slower than the newer Digix IV in getting the files out of the camera.
A better camera for this until the 5D mkII itself is evaluated by Rob, is the 50D, which does have both UDMA support, and the Digix IV. You will see how much faster each card is with this camera as opposed to the older 1Ds mkIII.
Yo Mel, I\'ll buy all your extreme III\'s for a buck!
When a camera\'s spec says a burst rate of 13 images, at 3.9 shots per second, thats all based on internal camera buffers and has nothing to do with the CF card. Rob Galbraith\'s test only timed the amount of time to write to the card, which had nothing to do with the total number of images in a burst, the frame rate or the cameras ability to write those images to internal memory.
So yeah, if you wanted to shoot 200 raw images at 10 frames per second, you\'ll need something faster than Ducati cards that can empty the buffer as fast as you shoot.
