	Linux software raid is capable of doing all the usual stuff as well as 
RAID 0+1 or 1+0. I'd want a RAID 0 stripe of mirrored RAID 1 sets rather 
than mirroring two RAID 0 sets, but my requirements may not be yours.

	Assuming this is a small home system I'd go with RAID 5 with maybe a 
hot spare if I have more than four drives in a normal server setting 
where reads happen more often than writes. That's more space with 
comparable performance for anything you're likely to be doing. If you 
really need the performance spend the money on a real RAID card with 
local cache. The difference is night and day.
