I would not make swap a RAID 0. Ever. It is fairly rare on systems to
actually use swap, so they don't need to be *that* fast. And if you lose a
drive, the system might chug along nicely until you try to access swap, in
which case I imagine the machine would crap all over itself. I would make
those partitions RAID 1, or perhaps a pair of RAID 1 md's with equal
priority.
