Traditionally a hardware RAID consisted of SCSI drives on systems with
slower bus speeds and you could actually improve performance but you are
talking about low end, SATA stuff on machines with higher bus speeds and
you really aren't getting improved performance and to get a true
hardware RAID SATA controller probably will push you out of the 'entry
server hardware' category. Recognize that the lower end SATA RAID
controllers aren't truly hardware RAID but are software RAID (Brian
calls them fake RAID or fRAID) and for simplicity it's typically better
to just use software RAID.
