Does swap need to be part of the RAID set? Is there actually a performance boost?
Not a performance boost, but if the drive that swap is on fails while the OS has data there the system can choke horribly or even die. Swap on raid can sometimes be slightly slower. If you think your system won't swap any critical sleeping processes, you could be safe. But who can be that sure?
