RAID is an acronym first defined by David A. Patterson, Garth A. Gibson, and Randy Katz at the University of California, Berkeley in 1987 to describe a redundant array of inexpensive disks,[1] a technology that allowed computer users to achieve high levels of storage reliability from low-cost and less reliable PC-class disk-drive components, via the technique of arranging the devices into arrays for redundancy.

Marketers representing industry RAID manufacturers later reinvented the term to describe a redundant array of independent disks as a means of dissociating a "low cost" expectation from RAID technology.[2]

"RAID" is now used as an umbrella term for computer data storage schemes that can divide and replicate data among multiple hard disk drives. The different schemes/architectures are named by the word RAID followed by a number, as in RAID 0, RAID 1, etc. RAID's various designs involve two key design goals: increase data reliability and/or increase input/output performance. When multiple physical disks are set up to use RAID technology, they are said to be in a RAID array[3]. This array distributes data across multiple disks, but the array is seen by the computer user and operating system as one single disk. RAID can be set up to serve several different purposes.

RAID stands for Redundent Array OF Independent Disk This technology is mainly used for hard disks to provide protection against hard drive failures and also to improvise performance.RAID builds on 2 primary concepts ? Striping (storing data across multiple disks sectors of multiple drives so that disk head can read more data in a single move) and Mirroring(replication of drives). RAID requires minimum of 2 disks & can have maximum of 32 disks. Source:
