What does RAID stand for in data storage?

Redundant Array of Isolated Disks

Rapid Access Information Disk

Redundant Array of Independent Disks

RAID stands for Redundant Array of Independent Disks. This term refers to a data storage virtualization technology that combines multiple physical disk drive components into a single logical unit. The primary purpose of RAID is to provide data redundancy and improve performance. By using multiple disks, RAID can help ensure that data remains accessible even if one or more disks fail, depending on the level of RAID implemented.

Each disk operates independently, which is contrasted with the notion of isolated disks. Therefore, the term “independent” is essential in describing how the disks function within this array system. Different RAID configurations can offer various levels of redundancy, performance enhancement, and data recovery options, making it a critical concept for data management and storage strategies in IT environments.
