2-3 RAID1
In RAID1, data saved to a HDD is written to another HDD without change. This mode is called "mirroring."
When data is written to a single HDD, the same data is written to another HDD. If either of the HDD
‟s fails,
the other HDD containing the same data can substitute for the failed HDD. Thus, the system can continue to
operate without interruption.
