While the advice is good... Blaming MS licensing isn't justified.  The
reason firmware raid exists is because, long ago, cpus were not powerful
enough to take this load on in addition to other tasks, so you needed
processors that sat on adaptor cards to handle the load.  These days, there
is plenty of cpu, so it no longer makes any sense.

These days, "hardware RAID" is just someone else's Linux box running
software RAID (ok, NETAPPS are Solaris'y).  There may be a few ASICS in
there, but by and large, it's software.
