What does RAID stand for?

RAID stands for Redundant Array of Independent Disks. This term refers to a storage technology that combines multiple physical disk drive components into one or more logical units. The primary purpose of RAID is to enhance data redundancy and improve performance, allowing for better data management and increased storage reliability.

The term "Redundant" signifies that RAID configurations typically involve duplicating the data across several disks. This redundancy is crucial for data protection, as it allows for continued data access and integrity even if one or more disks fail. "Array" indicates the grouped nature of these disks, and "Independent" highlights that the disks can operate independently while still functioning together as part of the RAID configuration.

Understanding the concepts behind RAID helps in recognizing its different levels, such as RAID 0, RAID 1, RAID 5, etc., each offering differing balances between redundancy, performance, and storage capacity.
