Which technology combines multiple hard drives for performance and redundancy?

• A. Local Area Network (LAN)
• B. Backup as a Service (BaaS)
• C. Redundant Array of Independent Disks (RAID)
• D. Integrated Data Management (IDM)

Answer: (C)

The technology that combines multiple hard drives for improved performance and redundancy is Redundant Array of Independent Disks (RAID). RAID combines multiple physical disk drive components into a single logical unit for the purposes of data redundancy, performance enhancement, or both. By distributing data across several drives, RAID can improve access speeds due to concurrent read/write operations, while also providing redundancy in case of a drive failure. Different RAID levels offer various balances between performance and redundancy, such as striping data across drives for speed or mirroring data to protect against data loss. Understanding RAID is essential for managing storage systems effectively, as it plays a crucial role in both personal computing and enterprise data storage environments.
