Stores identical data in multiple disks.

It is the act of splitting data and storing it randomly.

Detailed explanation-1: -RAID level 1 – Mirroring Data are stored twice by writing them to both the data drive (or set of data drives) and a mirror drive (or set of drives). If a drive fails, the controller uses either the data drive or the mirror drive for data recovery and continuous operation. You need at least 2 drives for a RAID 1 array.
Detailed explanation-2: -RAID 1+0 (10) With this RAID level, data is mirrored and striped simultaneously. Most often, this is implemented with four drives, and one mirrored drive set is striped. This provides even higher fault tolerance and performance.
Detailed explanation-3: -A RAID 1 configuration copies data from one drive to another, mirroring and duplicating data to provide improved fault tolerance and data protection.
