NO! For $DEITY's sake- NO! ssds can't withstand many writes (yeah, I know, millions blablabla... earlier done than you think). Do Not Do This.

How'd they work out? no, /var/tmp is very not important from a performance point of view - with the exception of /var/tmp/portage - and that is a candidate for tempfs. -- #163933
