RAID Level
Description
RAID 0
(at lease two hard disks/
SSDs needed)
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
(at lease two hard disks/
SSDs 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 replace-
ment drive is installed, data to the new drive is rebuilt from the mirrored drive to restore fault tolerance.
Recovery
(at lease two hard disks/
SSDs 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
.
