"RAID" stands for "Redundant Array of Independent Disks" in computer data storage. RAID technology is used to combine multiple physical disk drive components into a single logical unit for data redundancy, performance improvement, or both. Various RAID levels, such as RAID 0, RAID 1, and RAID 5, offer different balances of redundancy and speed. By distributing data across multiple disks, RAID provides fault tolerance and minimizes data loss risks in case of a disk failure. It is widely utilized in servers and enterprise storage systems to enhance data availability and reliability.
