Which of the following RAID levels provides the HIGHEST fault tolerance possible?

RAID 0 uses only striping with zero redundancy, so a single drive failure results in complete data loss.

RAID 5 uses single distributed parity and can tolerate only one drive failure before data loss occurs.

RAID 6 uses double parity and tolerates up to two simultaneous failures, which is better than RAID 5 but still less than the scalable multi-failure tolerance of RAID 10.

RAID 10 mirrors data across drive pairs and stripes across those pairs, so it can survive the failure of one drive in every mirrored pair simultaneously. Unlike RAID 6, which is hard-limited to tolerating exactly two failed drives, RAID 10 scales its fault tolerance with the number of disk pairs, making it the most resilient option listed.
