My 50D with UDMA card (measured at around 30 meg/sec) can shoot around 90 jpegs before slowing down (6.3fps), which is cool, but the impressive part is the speed with which it clears the buffer. If the buffer clears slowly it doesn't take a 40 jpeg burst to get into trouble, just shooting fast and frequent.
seems that is the ideal solution for the jpeg burst speed. I guess it's the same with the RAW which has a bigger file size. the buffer clearance is somewhat a concern if one is shooting above 40 jpegs or 14 RAWs on action photography. but that is still an enigma since I haven't tried doing that myself yet. the max jpeg burst shot that I did was only 20 jpegs. on a normal burst shooting, 6 jpegs is a standard.
I guess there is no need for a much faster SDHC card then and a class 6 would do the job for both pictures and video recording.
