What does the acronym RAID 0 signify?

• A. Redundant Array of Independent Disks; data mirroring
• B. Redundant Array of Inexpensive Disks; for fault tolerance
• C. Redundant Access for Independent Devices; for better performance
• D. Striping without redundancy, increasing performance but not fault tolerance

Answer: (D)

The acronym RAID 0 stands for "Redundant Array of Independent Disks," and it specifically refers to a configuration where data is striped across multiple disks. This striping process enhances performance by allowing simultaneous read and write operations across the different disks, effectively increasing input/output (I/O) throughput. However, a critical characteristic of RAID 0 is that it offers no redundancy or fault tolerance. This means that if any single disk in the RAID 0 array fails, all data within that array is lost, since there are no copies or mirrors of the data stored anywhere else. Therefore, while RAID 0 improves performance, it does not provide a safety net for data protection, making it essential to have backups or alternative data protection strategies when using this RAID level. In summary, RAID 0 is focused on maximizing performance through striping, and the absence of redundancy is a key feature that distinguishes it from other RAID configurations that include data protection mechanisms.
