Once I started shooting RAW all the time, I shot RAW + JPG while traveling because my traveling computer didn't meet installation requirements for my RAW editing program. Then I remembered dcraw.J.J.B. wrote:Regarding RAW vs JPEG, I tend to shoot in both. My Nikon D200 has the option to shoot both modes so I can use the JPEGs for 'quick and dirty' shoots where I need to just get some shots, but then if they don't come out quite right I will revert back to the RAW file for colour correction.

RAW files contain a JPG so the camera can show what it just shot. dcraw extracts those JPGs. Fast. Runs on Windows, Mac and Linux. Two ways to use it. First is command line:
$ dcraw -e *.CR2
(or whatever the three letter file extension your camera manufacturer uses)
Second way is a program that calls dcraw. These range from simple to complex. Windows has RawDrop that works as simple as the name: drag & drop your RAW files on the open app and it spews JPGs into the same directory.
You'll save camera battery and get a higher frames per second by shooting RAW and extracting the JPGs later on your computer.
