What is RAID 1 commonly referred to as?

  1. Disk striping

  2. Disk mirroring

  3. Error correction

  4. Data recovery

The correct answer is: Disk mirroring

RAID 1 is commonly referred to as disk mirroring because it creates an exact copy of the data on one disk onto another disk. This means that all information stored on one disk is duplicated on a second disk, providing redundancy. In the event of a disk failure, the data remains accessible from the mirrored disk, which enhances data availability and security. This mirroring process is crucial for ensuring data integrity, as it protects against data loss. RAID 1 is typically used in environments where data reliability is critical, such as in business applications where downtime can lead to significant financial losses. This characteristic directly distinguishes it from the other options listed, such as disk striping, which involves distributing data across multiple disks to improve performance rather than redundancy.
