You can do this yourself, and end all the speculation... :idea:

It doesn't end the speculation, 'cos testing the card in a reader is one thing, but my camera isn't a P4 running XP on USB2, so what matters is the camera to card and buffer interface - and that's always likely to be the limiting factor in deciding whether to get a faster more expensive card.

So the link is very handy to compare cards and in their cluster size formats - even useful to get a feel for data transfer speeds across a reader interface, but it may not always help determine the card performance in the camera, which matters most! VOX
