Given the drive performance varies so widely with your selected applications there is no best setup. Try your possible setups and benchmark it. Then use the best results.

" (100mb): temporary file partition holding temp and temporary internet files "

I have some video editing and the temp files zoom into the gigabytes so this is a fine example where such a setup would fail for me. I can't tell if you do such so I can't tell you if this is a bad setup.
