What are y'all using the ram disk for? I see it there but never thought to use it for anything.
I download files there before copying them to HD (SFS framgents too badly if you have simultaneus downloads or if I don't want to keep downloaded file anyway (like some crap videos etc you are mistaken to dl)).
I unpack program archives there for installing (useless to have them on HD if it has separate installer).
I give test run for unpacked games etc from ram: if they are worth to keep or not (useless copies to HD again if I only want to run it once and get rid off it after that).
I throw all kinds of temp/test files there (image/video/audio processing stages)... etc..
