Swap in RAID1?

Since you must treat your swap space as an extension of RAM, you should
keep it on the RAID partition.  To do otherwise would be like ripping
out one of your DIMMs with the machine on.  But I suppose it also
depends on what else you leave off the RAID.  If you only RAID your
data, then perhaps it is less important that you mirror your swap.  This
goes back to the fundamental question: What problem are you trying to
solve with the RAID array?  RAID0 is great to solve size and speed
issues.... but would you want to rely on it for fault tolerance?  Of
course not.

I see no reason why the machine will crash if you lose a hard drive.
That's part of the point of a RAID array.  Albeit I'm still a n00b in
Linux SW RAID so perhaps that's not the case.  HW RAID will not crash if
you have everything RAID1 or better.
