Advantages of RAID 1
- RAID 1 provides applications with increased data security. In case, one of the disks fails, the other disk contains a duplicate copy of the same data. Thus, RAID 1 provides a good fault tolerance.
- Data redundancy is provided in RAID 1.
- RAID 1 provides good performance for the read operation.
Disk Mirroring (RAID 1)
RAID 1 stands for Redundant Array of Independent Disks 1. RAID 1, also known as disk mirroring, is the technique of storing a copy of the same data in another disk. Here, the data is not broken into blocks rather a duplicate copy of the data is stored in another disk. A minimum of 2 disks are required in RAID.
Supposing, we have some data namely, D1, D2, and D3. In RAID 1, along with these original data we store copies of these data in another disk. Below is a diagram justifying the above statement and thus explaining the concept of RAID 1.
