data 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

existing drive and a new drive for this setup. The new drive must be of the same

independently and does not provide fault tolerance or other RAID performance
