RAID is an acronym for what?

RAID stands for Redundant Array of Independent Disks. This technology is used to combine multiple physical disk drive components into a single logical unit for improved performance, redundancy, and availability of data. The concept behind RAID is to spread data across several disks, allowing for greater speeds and reliability.

The term 'redundant' is key here because RAID setups often provide a backup in case one of the drives fails, thus protecting data against loss. This redundancy can be implemented in various RAID configurations (like RAID 0, RAID 1, RAID 5, etc.), each with its own balance of performance and data protection.

Other options provided do not represent the widely accepted definition of RAID. They incorporate components of technology terminology but do not accurately describe what RAID means or its functions related to disk storage systems.
