You handle a RAID 0 drive exactly as you would any other drive -- the
spanning is transparent to the user.

As to the PS scratch space -- you really have to decide this according to
your circumstances.

In general, the RAID partition would be faster, but not by as much as you
might think, since it would also be creating more seeks on the primary
drive, thus slowing it down quite a bit.
