disable jpeg save in raw+ jpeg mode

If the above were an option then there might be a slight increase in raw save mode, especially in continuous mode.
I wonder if our cameras capture in raw and then downconvert to jpeg. If so, then time saved in not saving to card the jpeg might be minimal.

Same answer I gave when you asked this yesterday :

Essentially.  RAW is just the sensor image - the camera reads that image into a buffer and then does quite a bit of image processing, including jpeg encoding.

True.
