RAID 1, also known as mirroring, involves copying the same data on two hard drives. In the event of a drive failure, the system can immediately switch to the other drive without any data loss or downtime, effectively shortening the recovery time objective (RTO) for a firm. RAID 5 also provides redundancy but involves striping with parity, which can slightly delay recovery due to the need to reconstruct data from the parity information. RAID 0 focuses on performance rather than redundancy and does not provide any fault tolerance. RPO (Recovery Point Objective) is a measure of the maximum tolerable period in which data might be lost due to a major incident, not a configuration that affects recovery time.
