I've googled this question without a great deal of information.
Of couse will be creating RAID0 swap but leaving that out of the question for obvious reasons.
You really should use anything but RAID 0 for swap. If you need to swap and that device is dead then your system is hosed.
At one point I read that you can get RAID0-"like" performance by having multiple swap partitions on multiple devices and mounting them with the same priority(mount option pri=(some number)). It (was/is) supposed to stripe the swap partitions. Not sure if that ever worked, though I have configured systems over the years to use matching swap priorities, never really looked to see if it was doing what I expected though.
Yeah, from swapon(2): [..] If two or more areas have the same priority, and it is the high-est priority available, pages are allocated on a round-robin basis between them.
