What can write data on two disks at the same time to duplicate the data?

A RAID 1 (Redundant Array of Independent Disks) configuration can write data on two disks simultaneously to create an exact duplicate. In this setup, data is mirrored across the disks, ensuring that if one disk fails, the other contains an identical copy. This redundancy enhances data reliability and availability. Additionally, certain disk cloning software can also write data to multiple disks at the same time for backup purposes.
