RAID Setup

You may use your hard disks in combination with Strip-
ing (RAID 0), Mirroring (RAID 1), Parity Across Disks
(RAID 5) or Recovery for either fault tolerance or perfor-
mance.
Prepare the following before setting up your serial ATA
hard disks in RAID mode:
• The Microsoft Windows OS disc.
• A second hard disk installed in the Primary HDD bay for
RAID level 0 or 1 or Recovery
OR
A second hard disk installed in the Primary HDD bay, and
a third hard disk in the Secondary HDD bay for RAID
level 5.
• The Device Drivers & Utilities + User's Manual disc.
