Which RAID level provides disk striping with NO redundancy?

Correct answer: RAID 0

Option C is correct because RAID 0 uses disk striping to distribute data across two or more drives for improved read and write performance, but it provides absolutely no redundancy. If any single drive fails, all data is lost, making it suitable only where performance matters more than data protection. Option A is wrong because RAID 5 uses block-level striping with distributed parity across at least three drives, providing fault tolerance for a single drive failure. Option B is wrong because RAID 1 is disk mirroring, which writes identical data to two or more drives simultaneously, offering full redundancy at the cost of usable capacity. Option D is wrong because RAID 10 combines mirroring and striping, requiring at least four drives, and provides both performance and redundancy by tolerating the failure of one drive per mirrored pair.
