Sure, but you have to reboot, and you just lost anything that was
happening when the disk failed. To me, if you do raid at all, then you
put swap on raid. I imagine it is quite possible to corrupt the data if
the system can't access half of swap and just crashes.
Besides with the price of ram, a system shouldn't normally be swapping
anyhow, so any minimal performance difference isn't worth considering.
Neither is the cost of disk space for doing raid for swap.
