RAID 5 requires a minimum of three drives. This is because RAID 5 uses block-level striping with distributed parity, which means that the parity data is distributed across all the drives in the array. This provides fault tolerance and allows for data recovery in the event of a drive failure. However, if only two drives were used, there wouldn't be enough parity information to rebuild the data if one of the drives failed.
