Disk mirroring, also known as RAID 1, is a fault tolerant disk arrangement that uses half of your disk space for fault tolerance. It maintains an exact copy (mirror) of data on two separate disks, so if one disk fails, you still have a complete copy of all data on the other disk. Disk striping (A) and disk striping with parity (C) both use more than half of your disk space for fault tolerance and are not as efficient as disk mirroring. Disk parity (D) is not a valid type of disk arrangement.
