What is RAID?

RAID failure- Dos and Don’ts

RAID stands for ‘Redundant Array of Independent Disk’ or sometimes known as ‘Redundant Array of Inexpensive Disks’. In simple terms, a RAID is a way of logically putting multiple disks together into a single array. When numerous disks are placed together, the performance and/or reliability of a system are optimized for fast and better performance. There are different types of RAID configurations depending on the choice of preference.

RAID is finding most helpful when it comes to protecting crucial data from catastrophic situations. This powerful configured system is reliable to keep data protected but doesn’t mean it’s damage-proof.
