/, a small swap, /usr, and maybe /var, should be on your boot spindle
More swap, /tmp, and /local, /home, etc., should be on the second
I just think about how the system will access various files, and I try
to split major groups of file accesses across each available spindle,
minimizing potential contention as much as possible.
The secondary goal is to make filesystems for each major "sub-system"
you run, such that any one of them can run out of space, and not affect
the others, *or* the basic operation of the system. I.e. if you have
users on the system, /home should be separate, and most users should not
have write permissions anywhere else but /tmp, /var/tmp, and /var/spool.
If you expect your system to do much paging, make as many swap partitions
as you have spindles, with the smallest ones on the busiest spindles.
