You'll get the same benefits by using Linux's software RAID + it's
easier to setup and you won't be "vendor tied", i.e. if the
motherboard packs up and you can't get exactly the same one, or
another one with the same RAID chipset. You simply put the drives into
another PC and you're up and running again.
