I have swap, /var, /usr/src, /usr/obj, /usr/ports and /usr/home (and various other scratch areas) on a raidz on four real (SATA) disks. /tmp is a tmpfs. Seems to be working awesomely well. My /dev/gpt/root is mounted with soft-updates and noatime, in an attempt to keep writes down. (Which is also why /var and /tmp aren't on it.) Boot and OS/port updating is very fast. Well, fast enough for me. The SSD disk itself is an 8G compact flash card that I pinched from my camera bag, mounted in a SATA adaptor. Not because it's "best" or anything, but I thought that it could be handy to be able to rebuild or replace my "OS" off-line more easily. Cheers, -- Andrew
