Overview

From Wikipedia, the free encyclopedia · Read full article · Text CC BY-SA 4.0

RAID 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, the RAID system distributes the data across the array. There are several possible ways of doing this, and those various configurations are called RAID levels.
