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:
1. The Microsoft Windows 8.1 OS disc.
2. A hard disk installed in the Primary HDD bay.
3. A second (identical) hard disk installed in the Secondary HDD
bay.
4. The Device Drivers & Utilities + User’s Manual disc.
5. A USB flash drive.
6. An operable computer (to copy files from the Device Drivers &
Utilities + User’s Manual disc to the USB flash drive).
Note: All hard disks in a RAID should be identical (the
same size and brand) in order to prevent unexpected sys-
tem behavior.
RAID Level Description
RAID 0
(at lease two
hard disks
needed)
Identical drives reading and writing data in par-
allel 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 separate disk drive.
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 mir-
rored drive to restore fault tolerance.
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.
