Raw, unadulterated speed.  We've recently had to convert machine with
software RAID to hardware based RAID because we have so many clients
booting/running from it (NFS root). The HW RAID keeps up, AND, doesn't
take down racks of machines to rebuild an array when a drive is shot.

Yes, you can tune those parameters in SW RAID, but when you get to the
point that the throughput is down to the same rate as changes (which
is where the racks of nodes would function), what's the point of it
being RAID in the first place?
