RAID (Redundant Arrays of Independent Disks)
RAID (Redundant Arrays of Independent Disks) is a technique that makes use of a combination of multiple disks for storing the data instead of using a single disk for increased performance, data redundancy, or to protect data in the case of a drive failure. The term was defined by David Patterson, Garth A. Gibson, and Randy Katz at the University of California, Berkeley in 1987. In this article, we are going to discuss RAID and types of RAID their Advantages and disadvantages in detail.
