Which of the following RAID levels offers the HIGHEST level of protection with the shortest rebuild time?

RAID 3 uses byte-level striping with a dedicated parity drive, offering good performance for large sequential reads but has slower rebuilds as parity must be recalculated and written across all drives.

RAID 5 uses block-level striping with distributed parity, providing good performance and fault tolerance but rebuild times can be lengthy and impact performance significantly during the rebuild process.

RAID 6 uses block-level striping with dual distributed parity, offering better fault tolerance than RAID 5 (can withstand two drive failures) but has longer rebuild times and higher write overhead due to calculating and writing two parity blocks.

RAID 10 (or RAID 1+0) combines mirroring (RAID 1) with striping (RAID 0), offering excellent performance and the highest level of data protection with the shortest rebuild times because it only needs to copy data from the surviving mirror set, not reconstruct it from parity.
