if swap on /dev/hda goes bad ... the system wont know its bad
and you'd start eating yourself ( or for whatever reason hda went bad )

whether to put swap on raid1/raid5 or no raid seems to be the same as
(unsolvable) vi vs emacs issues
in my book, don't put swap on raid ... it'd be pointless..
if things are in swap and the system crashes .. swap is useless
- what is swap being used for ???
- if the system is using swap .. add more memory !!!
if a disk dies ... whether you put swap on raid or one on each disk
is a "that's why you get paid to make these choices"
