A mirrored volume is a storage configuration that uses at least two physical hard drives to maintain an exact, real-time copy of the same data on each drive, providing fault tolerance. If one drive fails, the system can automatically continue to operate using the other drive, and the data can be recovered or the failed drive replaced without any loss. This setup, commonly known as RAID 1, sacrifices storage capacity efficiency for data redundancy, as the total capacity of the mirrored volume is limited to the size of the smallest drive in the array.

Key features of mirrored volumes

Fault tolerance: The primary function is to protect against data loss if a drive fails. When one drive fails, the other continues to function as a single logical volume.

Redundancy: The system creates a perfect copy of the data, making the drives mirror images of each other.

RAID 1: Mirrored volumes are the most common implementation of RAID 1 (Redundant Array of Independent Disks).

Single logical volume: The operating system sees the mirrored drives as a single disk, hiding the complexity of the underlying physical drives.
