Just like raid 5, this does block level striping however, it uses dual parity in the above diagram a, b, c are blocks p1, p2, p3 are parities. Redundant array of independent disks (raid) storage uses multiple disks in order to provide fault tolerance and to increase storage capacity in a system.
Raid (redundant array of independent disks) is a disk system that contains multiple disk drives, called an array, to provide greater performance, reliability, storage capacity, and lower cost fault-tolerant arrays are categorized in six raid levels.
Raid levels used less raid 2 this was used with very large computers special expensive disks and a special controller are needed to use raid level 2.
