Sorry, "drive" in last sentence should be "driver"!

It could just be me, but I swear Hardware RAID has been faster for many
many years, especially with RAID5 arrays - or anything that requires
parity calcs.  Most of my benchmarking was done on SCO OpenServer and
Novell UnixWare and Netware, but hardware RAID controllers were always
faster and of course required far less host CPU resources.  Raid
0/1/10/0+1/whatever arrays, I recall weren't as drastic, but I can't
imagine the controller making as big a difference as the drives in the
array - unless of course the drive for said controller sux!
