Explanation
RAID 1 (mirroring) is the only option that provides data protection from hard drive failure using a minimum of two hard drives. In a RAID 1 configuration, an exact copy of the data is simultaneously written to both disks. If one disk fails, the data is still accessible on the remaining drive, ensuring no data loss and continuous operation. This makes it ideal for critical data on a workstation with limited drive capacity.
