Which RAID configuration is best suited for high read speeds and fault tolerance, with low risk of multiple drive failures?

The correct answer is RAID 10, which is known for providing both high read speeds and fault tolerance while also minimizing the risk of multiple drive failures. RAID 10 combines the benefits of RAID 0 (striping data across multiple drives to increase performance) and RAID 1 (mirroring data for redundancy). In this configuration, data is striped across mirrored pairs of drives, meaning that not only does it enhance read speeds, but it also ensures that there is a backup of the data on mirrored drives.

RAID 10 can tolerate the failure of one drive in each mirrored pair, making it more resilient than other configurations like RAID 5 or RAID 0. While RAID 5 offers error correction and better storage efficiency through parity, its performance can suffer during write operations, and it is at a higher risk of data loss if multiple drives fail, especially during the rebuilding process after a drive failure. RAID 0, on the other hand, provides excellent performance but does not offer any fault tolerance, meaning that the failure of just one drive results in the loss of all data in the array. RAID 1 provides fault tolerance through mirroring, but it lacks the performance advantages found in RAID 10 and does not have the increased read speed and efficiency
