Explanation
RAID 0 (striping) splits data evenly across two or more drives to increase total storage capacity and read/write performance. It provides no redundancy whatsoever - if any single drive fails, all data is lost. RAID 1 mirrors data, RAID 5 uses distributed parity for fault tolerance, and RAID 10 combines mirroring and striping for both performance and redundancy.
