Which RAID level uses data striping with a dedicated parity drive?

• A. RAID Level 0
• B. RAID Level 1
• C. RAID Level 3
• D. RAID Level 6

Answer: (C)

The option that correctly identifies a RAID level using data striping with a dedicated parity drive is RAID Level 3. In RAID Level 3, data is striped across multiple drives, which improves performance by allowing simultaneous read and write operations. Additionally, it employs a dedicated parity drive, which is crucial for data recovery. This setup enhances data reliability because if one of the data drives fails, the lost data can be reconstructed using the parity information stored on the dedicated drive. This combination of data striping for performance and dedicated parity for redundancy makes RAID Level 3 effectively suited for applications where high-speed data access is needed alongside fault tolerance.
