I just tested my CF cards for RAW write performance using the criterion set at the Rob Galbraith page (http://www.robgalbraith.com/bins/multi_page.asp?cid=6007-6432) and found that my new Ridata 2GB 52x Pro cards deliver 1758kB/s which puts them just slightly behind the Sandisk Ultra II and Extreme in his table. My old 512MB CF cards were spec'd at 20x and came in at 1566kB/s. I'd be interested to see what difference if any the new Write Acceleration technology might make. What it boils down to is that if you need to engage in continuous shooting in RAW past the 5 image buffer you'll be looking at about 7seconds at the very least between subsequent images even using the fastest CF cards. If you need to keep the buffer empty you need to shoot JPEG.
