Software RAID is perfectly acceptable.  Even a Sun E450 does software raid
amongst its internal drive arrays.  (You can get an external StorEdge
RAID5 array, but internally it's all software by default.  Yeah, I guess
you can get an internal RAID controller, too, but it's even more expensive
there than on x86).

What's the CPU requirement under Linux to (successfully) do a good
software RAID5?
