RAID (redundant array of independent disks)


A collection of hard disks used to form a RAID.

RAID stands for "redundant array of inexpensive disks" or "redundant array of independent disks". RAID is a type of data storage virtualization technology that writes data across several disk drives present in the same unit, to improve performance and data redundancy. The disk drives are combined into one unit, as if it were a more expensive disk, with more speed and durability, by storing data in all drives rather than specific ones.
