Which RAID level requires a minimum of four hard drives?

Answer options

• A. RAID 0
• B. RAID 1
• C. RAID 5
• D. RAID 6

Correct answer: D

Explanation

RAID 6 requires at least four hard drives because it uses two disks for parity, allowing for the failure of up to two drives without data loss. In contrast, RAID 0, RAID 1, and RAID 5 can function with fewer drives, making them less demanding in terms of minimum drive requirements.
