A RAID 1 (mirroring) set will provide redundancy, or protection against one of the drives failing during use. With a RAID 1 disk volume, information is written to the first drive and then to a second (or “mirror”) drive at the same time. If one of the hard drives in the mirror volume fails, the remaining hard drive can be placed in service as a single drive with no loss of information. Similar to a RAID 0 (striped) volume, RAID 1 volumes require a minimum of two (2) drives.
