What does RAID stand for?

• A. Redundant Array of Independent Disks
• B. Redundant Array of Inexpensive Disks
• C. Random Access Internal Disks
• D. Rapid Access Interconnected Disks

Answer: (A)

RAID stands for Redundant Array of Independent Disks. The idea is to combine several separate disks into one logical storage unit to improve reliability and/or performance. Redundant means data protection against a disk failure, achieved through mirroring or parity. Array signals a collection of disks treated as a single resource, and independent emphasizes that these are individual disks working together. In many contexts, this exact expansion is used, though historically some sources spell it Redundant Array of Inexpensive Disks. The other options describe attributes that aren’t part of the established acronym, such as random or rapid access, which don’t convey the coordinated use of multiple disks for redundancy and performance.
