Usually. Are you going to be doing a lot of compiles or newsfeeds or
other things that want to beat on two areas (/tmp and . or /usr/lib
for the one, in.coming and newsspool for the other). With two spindles
you get minimum seeking, since you don't have to keep switching between
active areas.

Also, with 2 disks you have easier recovery if you lose one.
