RAID Setup

You may use your hard disks in combination with Striping
(RAID 0), Mirroring (RAID 1), Parity Across Disks
(RAID 5) for either fault tolerance or performance.
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 5
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.
RAID Hard Disks
All hard disks in a RAID should be identical (the same
size and brand) in order to prevent unexpected system
behavior.

RAID 1 (mirrored array) provides full data protec-

disk to a replacement for any failed disk.
