Raid (Redundant Array of Independent Disks) is a type of data storage technology that combines multiple physical hard drives into one logical unit. It works by mirroring data across multiple disks to create redundancy, which ensures that data remains safe and intact if a drive fails. Raid systems can also improve performance by distributing data across multiple disks, allowing multiple drives to access the same data at the same time. Raid levels are categorized by the way data is distributed across the disks, with each level offering a different set of benefits. The most common Raid levels are 0, 1, 5, 6, and 10.
