Explanation

RAID 0 (striping) splits data evenly across two or more drives, allowing simultaneous read/write operations. This delivers the highest raw disk performance of all RAID levels because there is no redundancy overhead - all drive capacity and I/O throughput is dedicated to performance. Since the customer already has a separate NAS handling backups, data redundancy from the RAID array itself is not required, making RAID 0 the optimal choice. RAID 1 (mirroring) offers redundancy but no performance gain. RAID 5 provides redundancy with moderate performance but incurs parity calculation overhead. RAID 10 offers both performance and redundancy but requires at least four drives and sacrifices half the total capacity.
