and to add to that i just did a test - full quality jpeg+raw on continuous shoot on the same subject (a sheet of white paper with writing on it - held the shutter release until "failure" on my 2gig and my 4gig card.

2 gig card took 7 shots (the buffer size i assume) and then paused slightly and then shot an 8th shot (obviously the buffer had cleared the first shot by the time the 7th shot had been taken) so from start to finish it too 15.5 seconds for the red "processing" light to go off.

4 gig card took 7 shots and even tho i did hold the shutter realease to see if it would take another it didnt... so i sat and waited for 38.5 seconds for the light to go off.

So obviously the performance isnt there. although i have to say (through actually getting the card up to around the 3.5gig mark on a day of shooting) the storage is - not sure what putting it in 50 degrees would do to it tho ;)
