RAID Levels Supported By Windows
Server 2012
RAID 0 (Disk striping)
Two or more volumes, each on a
separate drive, are configured as a striped set. Data is broken into blocks,
called stripes, and then written sequentially to all drives in the striped set.
Advantages: Speed and performance.
RAID 1(Disk mirroring)
Two volumes on two drives are
configured identically. Data is written to both drives. If one drive fails, no
data loss occurs because the other drive contains the data. (This level doesn’t
include disk striping.)
Advantages: Better write performance
than disk striping with parity.
RAID 5(Disk striping with parity)
Uses three or more volumes, each on
a separate drive, to create a striped set with parity error checking. In the
case of failure, data can be recovered.
Advantages : Fault tolerance with
less overhead than mirroring. Better read performance than disk mirroring.
