A RAID (Redundant Array of Independent Disks) controller is a hardware device or a component of the storage subsystem that manages the process of combining multiple physical disk drives into a single logical unit. The primary objectives of a RAID controller include data redundancy, improved performance, and fault tolerance.

RAID configurations are widely adopted in enterprise environments to enhance data reliability and performance. By distributing data across multiple disks and creating redundant copies, RAID protects against data loss due to disk failures. Additionally, certain RAID levels offer improved read and write speeds, contributing to overall system efficiency.
