5.4.1 RAID denitions

RAID 0

in parallel, interleaved stacks. Two hard disks perform the same work as a single

drive but at a sustained data transfer rate, double that of a single disk alone, thus

improving data access and storage. Use of two new identical hard disk drives is

required for this setup.

RAID 1

(Data mirroring)

copies and maintains an identical image of data from one

drive to a second drive. If one drive fails, the disk array management software directs

all applications to the surviving drive as it contains a complete copy of the data in

RAID 5 stripes both data and parity information across three or more hard disk drives.

drives for this setup.

JBOD

Spanning does not deliver any advantage over using separate disks independently
