RAID 5 requires at least 3 drives and uses parity checking to provide fault tolerance. Data is striped across the drives with parity information stored on each drive. This means that if one drive fails, the data can be reconstructed using the parity information on the remaining drives. RAID 5 provides both performance improvement and fault tolerance.
