The system board is equipped with two shrouded RAID IDE
headers that will interface four Enhanced IDE (Integrated Drive
Electronics) disk drives. To prevent improper IDE cable installation,
each shrouded RAID IDE header has a keying mechanism. The 40-
pin connector on the IDE cable can be placed into the header only if
pin 1 of the connector is aligned with pin 1 of the header.
Hard drives must be Ultra ATA/133, ATA/100, Ultra ATA/66, Ultra
ATA/33, EIDE and/or Fast ATA-2 compatible. For optimal
performance, install identical drives of the same model and capacity.
The drives’ matched performance allows the RAID array to function
better as a single drive.
Drives in an array must be identical. If striping for performance, use
two new drives. If mirroring for protection, you can use two new
drives or use an existing drive and a new drive (the new drive must
be the same size or larger than the existing drive). Only two drives
can be configured as RAID. Since both of these drives must be in
Master mode, striping or mirroring must be done between 2 RAID
IDE channels; not between 2 drives that are chained on the same
channel.
