I agree with that. One generally uses RAID to keep a host running when
a disk failure occurs. If swap is not mirrored, processes wil crash,
or worst case the box might crash.

If performance is an issue, then you'd better go hardware raid.

Unless someone knows of another strong reason not to put swap on raid?
