RAID 5 requires at least three drives and uses parity checking to provide fault tolerance. Data is striped across the drives, meaning that it is divided into pieces and distributed across all drives in the array, rather than being mirrored on another drive. RAID 5 also provides improved read and write performance compared to a single drive, as data can be accessed from multiple drives simultaneously.
