Looks good! I'll have to bear these in mind. I just bought an SD card from SanDisk which has read and writes of around 95mb/s.

Nice, I really like sd cards for portability and convenience. It's not only cameras that have benefitted from faster and higher-capacity sd cards though. I have a Zoom R24 multitrack recorder that uses them and also can run off 6xAA batteries. Unimaginable even 10yrs ago. At these kind of speeds they would be great even for laptops. Now, if we could only install windows to these cards without hacks and utilise them like a raid configuration with multiple cards...
