RAID 10, also known as RAID 1+0, combines disk striping and mirroring to achieve both high performance and redundancy. In this configuration, data is mirrored across multiple drives for fault tolerance, while striping ensures improved read and write performance. This setup offers better performance compared to RAID 5 and RAID 6, especially in environments with high I/O demands, such as databases and virtualization platforms.

RAID 5, while offering redundancy through distributed parity, can suffer from performance degradation during write operations due to the parity calculations. RAID 6 provides additional fault tolerance with dual parity, but it incurs higher overhead and may not offer the same level of performance as RAID 10, especially in write-heavy workloads.

RAID 50 combines the striping of RAID 0 with the redundancy of RAID 5, but it may not always provide the optimal balance between performance and redundancy, especially in scenarios where random I/O performance is crucial.

Therefore, for Mr. Anderson’s scenario where performance and data redundancy are paramount, RAID 10 is the most suitable choice.
