RAID: Standards & History

RAID (Redundant Array of Inexpensive Disks) is an orchestrated approach to computer data storage in which data is written to more than one secondary storage device. Instead of storing all data in a single hard disk drive or solid-state drive, RAID coordinates two or more such devices into a disk array. When the computer writes data to secondary storage…
