RAID implementation

RAID implementation improves data storage reliability and performance.

Redundant array of independent disks (RAID) is a method of configuring multiple
drives in a storage subsystem for high availability and high performance. The
collection of two or more drives presents the image of a single drive to the system.
If a single device failure occurs, data can be read or regenerated from the other
drives in the array.
