RAID Setup
You may use your hard disks in combination with Striping
(RAID 0), Mirroring (RAID 1), or Recovery for either
fault tolerance or performance.
Table 2 - RAID Description
Prepare the following before setting up your serial ATA
hard disks in RAID mode:
• The Microsoft Windows 7 OS disc.
• The Device Drivers & Uti 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.
RAID Setup Procedure
Part I: BIOS
1. Start-up your computer and press F2 to enter the BIOS .
2. Go to the Advanced menu, select SATA Mode and press
Enter.
3. Select RAID Mode .
4. Press Esc and go to the Boot menu.
5. Set the CD/DVD-ROM Drive (make sure the Microsoft
Windows OS disc is inserted) as the first device in the boot
order from the Boot menu.
6. Select Save Changes and Reset from the Exit menu (or press
F4 ) and press Enter to exit the BIOS and reboot the computer.
RAID Level Description
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
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.
RAID 1 (mirrored array) provides full data pro-
tection, as data can simply be copied from a
healthy disk to a replacement for any failed disk.
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
Win-
dows Explorer .
