A [[wikipedia:disk array]] is a disk [[storage system]] which contains multiple disk drives ([[Hard disk drive|HDD]] or [[SDD]]). It is differentiated from a disk enclosure by providing additional functionalities and capabilities such as fault tolerant designs, cache memory, different [[RAID]] levels, [[deduplication]], [[cryptography|encryption]] and even [[virtualization]]. | A [[wikipedia:disk array]] is a disk [[storage system]] which contains multiple disk drives ([[Hard disk drive|HDD]] or [[SDD]]).
