In the HD Record tests we start to see the 1GB of system RAM come into play as we move to more advanced RAID.
RAID 5 and RAID 6 performance declines quite a bit in several tests even though we're using eight drives. The high drive count normally counter acts the performance loss associated with redundant RAID.
