JPEG are almost always faster. The bottleneck is the bus to the memory card, if not the memory card. A faster memory card only shifts the bottleneck from the card to the bus but that will be your limit in terms of speed. This is because JPEG files are smaller by at least 50% and sometimes much more if you enable on of the lower-quality settings which ...

First - do you have a specific problem? The time to dump an image to the memory card varies a lot from camera to camera and the best solution for your problem is probably to try to investigate it yourself. Also why are you focusing on the time it takes dump the file to the memory card? With the often large buffers of modern cameras you can often continue to ...

It depends. There is not only one factor. RAW also have compression (in generally), but lossless, like zip. And depend of entropy (how much different information you have in picture) can produce different files. For example my camera produce from 25MB to 38MB RAW files. High ISO produce more noise and as result bigger files JPG files are compressed with ...

Since you asked why: the reason for this is that the files on the camera are stored using a very simple filesystem using 8.3 file names, which by default are upper-case (originally these filesystems didn't distinguish between upper and lower case in filenames). There's an option in Linux (shortname=lower) that can be used when mounting the USB storage which ...

Renaming file do not change the content of the file. So you should not be afraid of this. Renaming of the file is operation, related to the metainformation of your picture, stored in the filesystem and it is not related to the content of the file itself
