3kramd5 - I shoot JPEG with the various adjustments and RAW in the hope that I've got something to work with if I cock up. Also, as you are probably aware, the SD card slot is crippled and it's faster to save JPEGs to SD.
I used to have the same thought, but you might want to test if "it" is really true. With "it" I mean: is the JPEG-conversion plus writing to SD card really faster than writing a larger RAW file away to the SD card?
I did this test a long time ago, but I think writing RAW files to the SD card was faster, because the camera doesn't need to convert to JPEG.
However, I still use the SD card as the place to store the JPEGs and the CF for the RAWs. Not only for backup reasons, but also to have the JPEGs immediately available for easy sharing to others and I also really like the quality of the in-camera processing.
