Question

Explanation

RAID 5 is the correct choice. It uses block-level striping with distributed parity across all drives, providing both improved write performance through striping and fault tolerance - the array continues operating if exactly one drive fails. With three drives, RAID 5 is the minimum and ideal configuration. RAID 0 offers great performance but has zero fault tolerance. RAID 1 (mirroring) provides fault tolerance but no write performance gain. RAID 10 requires a minimum of four drives. RAID 5 is the best balance of performance and redundancy with exactly three drives.
