RAID Setup - 5

RAID Setup
You may use your hard disks (if you have included more
than one hard disk in your purchase option) in combina-
tion with Striping (RAID 0), Mirroring (RAID 1), Parity
Across Disks (RAID 5) or Recovery for either fault tol-
erance 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 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.

RAID Level Description
Recovery
Two Identical drives co pying 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 read ing and writing dat a i n paral -
lel to increase performance. RAID 0 imple-
ments a striped d isk array and the data is broken
into blocks and each block is written to a sepa-
rate disk drive.
RAID 0 (a strip ed array) is n ot fault-t olerant. 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
contains identical data) will handle all the data.
When a new replacement drive is inst all ed, dat a
to the new drive is re built from the mirrored dri ve
to restore fault to le ra nc e.
RAID 1 (mirrored array) provides full data pro-
tection, as data can simply be copied fro m a
healthy disk to a replacement for any failed disk.
RAID 5
(three hard
disks
needed)
Identical drives (at least three drives must be
used) in a parity across disks configuration are
used to protect data and increase perfor-
mance. A RAID 5 array can withstand a single
disk failure without losing access to data.
