RAID 1, also known as disk mirroring, duplicates data identically to two drives, ensuring full redundancy if one drive fails. Because the workstation only has two drives, RAID 1 is the only RAID level that provides fault tolerance under this constraint, exactly as described in the CompTIA A+ study guide.
RAID 0 offers no redundancy, RAID 5 requires at least three drives, and RAID 10 requires at least four drives.
RAID 1 is the recommended configuration for small environments or workstations that rely on data integrity and quick recovery, matching CompTIA’s guidance for redundancy in systems with limited drive availability.
