You may use your hard disks in combination with Striping
(RAID 0), Mirroring (RAID 1) or Recovery for either
fault tolerance or performance.
Table 1 - RAID Description
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
.
