(Redundant Array of Independent Disks) is a data storage technology that combines multiple physical hard drives into a single logical unit to improve performance, provide redundancy, or both. RAID achieves this by distributing data across the drives in different configurations known as RAID levels (e.g., RAID 0, RAID 1, RAID 5). Each RAID level offers different benefits, such as increased speed (RAID 0), data mirroring for redundancy (RAID 1), or a combination of performance and fault tolerance using parity (RAID 5, RAID 6).
