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.
Table 2 - RAID Description
RAID Level Description
Recovery
(at lease two
hard disks
needed)
Two identical drives copying data between a
master and a recovery disk. This provides more
control over how data is copied between the
master and recovery drives, fast volume updates
and the ability to view the data in Windows
Explorer.
RAID 0
(at lease two
hard disks
needed)
Identical drives reading and writing data in paral-
lel to increase performance. RAID 0 imple-
ments a striped disk array and the data is broken
into blocks and each block is written to a sepa-
rate disk drive.
RAID 0 (a striped array) is not fault-tolerant. The
failure of one drive will result in the loss of all
data in the array.
RAID 1
(at lease two
hard disks
needed)
Identical drives in a mirrored configuration used
to protect data. Should a drive that is part of a
mirrored array fail, the mirrored drive (which con-
tains identical data) will handle all the data.
When a new replacement drive is installed, data
to the new drive is rebuilt from the mirrored drive
to restore fault tolerance.
RAID 1 (mirrored array) provides full data protec-
tion, as data can simply be copied from a healthy
disk to a replacement for any failed disk.
