RAID Setup (Models C & D
Only)
You may use your hard disks in combination with Strip-
ing (RAID 0), Mirroring (RAID 1) or Recovery 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.
• The Device Drivers & Utilities + User's Manual disc.
Note: All hard disks in a RAID should be identical (the
same size and brand) in order to prevent unexpected sys-
tem behavior.
