Which method is used to configure several disk drives into a logical disk drive and provides faulttolerance, redundancy, lower latency, and higher bandwidth for read/write operations?

DRM (Digital Rights Management) is a content protection and licensing technology, not a disk management or storage configuration method.

DAC (Discretionary Access Control) is an access control security model that governs resource permissions based on user identity, not disk drive configuration.

RAID is the technology specifically designed to stripe, mirror, or combine disk drives into a logical volume, offering fault tolerance through redundancy and performance gains via parallel read/write operations across multiple spindles. Different RAID levels (0, 1, 5, 6, 10) balance these goals differently, but all meet the core definition in the question.

MAC (Mandatory Access Control) is a security policy model that enforces access based on classification labels, completely unrelated to disk drive configuration or storage performance.
