I have no experience or data on the DMR, but in what is otherwise one 
of the very fastest writing cameras, the Canon 1D MkII, the 
difference between the Sandisk Extreme III and the Ultra II is quite 
small and in practice would be hard to differentiate. Around 8Mb/sec 
is the top speed achieved.

Also note that in most cases, the fastest cards are the somewhat 
smaller sizes, ie 2Gb cards are almost always slower than 1Gb cards; 
again not a big or probably noticeable difference but on the same 
order as the difference between the Extreme III and the Ultra II.

The differences between these cards can well become important at some 
time, but that does not seem to be the case at present. If the DMR 
bogs down to write out the data after 10 shots at 2fps, then I don't 
think the write speed of the camera to the cards is going to be 
sufficient to allow the theoretically faster speeds of the Extreme 
III or the Ridata to shine.
