If one swap disk dies and you've been using it for swap, your system
will crash. If you use RAID 1 for swap, you can lose a disk and keep
running.

If your concern is for resilience, use RAID. If your concern is for
performance, use raw swap, as there is a performance hit with RAID,
because you have to write every page twice. It usually does the writes
in parallel, and you shouldn't notice a big decrease, but the
possibility is there.
