Setting Up SATA RAID
If your purchase includes the RAID (Redundant Array
of Independent Disks) option, the following pages pro-
vide an introduction to configuring your hard disk(s)
in RAID mode. You may use your hard disks in com-
bination with Striping (RAID 0) or Mirroring (RAID
1) for either fault tolerance or performance.
Table D - 4 - RAID Levels
Prepare the following before setting up your Serial
ATA hard disks in RAID mode:
1. An operable computer with a floppy drive (to create
a SATA RAID driver diskette).
2. The Device Drivers & Utilities + User’s Manual
CD-ROM.
3. An external USB floppy disk drive.
4. An external USB CD/DVD device drive (the
Microsoft Windows OS CD should be inserted into
this drive).
5. A prepared formatted blank 3.5" 1.44MB floppy
diskette.
6. The second hard disk installed in the optional
device drive bay.
RAID
Level
Description
RAID 0
Identical drives reading and writing data in parallel
to increase performance. RAID 0 implements a
striped disk array and the data is broken into blocks
and each block is written to a separate disk drive.
RAID 1
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 installed, data to
the new drive is rebuilt from the mirrored drive to
restore fault tolerance.
Array Types
A Mirrored Array (RAID 1) provides full data protection,
as data can simply be copied from a healthy disk to a re-
placement for any failed disk.
A Striped Array (RAID 0) is NOT fault-tolerant. The fail-
ure of one drive will result in the loss of all data in the ar-
ray. It is designed to increase disk performance by
spreading the I/O load across the channels and drives.
