Quote - Agreed, the max frame rate would be associated with a jpg file.
OTOH, comparing RAW with compressed RAW, I would expect the frame rate for RAW to be less than the frame rate for compressed RAW.

For most current DSLR cameras the max frame rate is almost the same whether shooting in RAW or JPEG (at least if judging from the manufacturers specs).
What is usually limited by shooting RAW is the number of shots you can take before the frame rate slows down due to buffer in the camera filling up.
For instance my Sony A200 will shoot at around 3fps in both RAW and JPEG, but wheras it can shoot at this rate until the memory card is full in JPEG mode it will only take about 7 pictures before slowing down when shooting RAW even with the fastest memory cards available.
A compressed RAW format should allow you to keep shooting at maximum speed for longer than with uncompressed RAW but in most DSLRcameras will have a minimal effect on the maximum frame rate which can be achieved.
