What is raid definition?

RAID (Redundant Array of Independent Disks) is a data storage technology that combines multiple physical disk drives into a single logical unit. The purpose of RAID is to improve data redundancy, availability, and performance. RAID works by distributing data across several drives, and in the event of a disk failure, allows for data to be reconstructed from other disks. There are several different RAID levels, each with their own characteristics, including RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, and more. Each RAID level offers a different combination of speed, data redundancy, and total storage capacity. RAID is commonly used in enterprise-level systems, but can also be used in personal computers and home media servers.
