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.

JBOD
(Spanning)
