Which option will protect data loss against catastrophic multiple physical drive failure?

RAID 10 is designed to provide high availability and data redundancy, making it an effective solution for protecting against catastrophic multiple physical drive failures. It combines the features of RAID 1 (mirroring) and RAID 0 (striping). By mirroring the data across pairs of drives, RAID 10 ensures that if one drive in a mirror fails, the data is still accessible from the other drive in the pair. The striping aspect improves performance by allowing read and write operations to happen concurrently across multiple drives.

In a scenario where multiple physical drives fail, RAID 10 can sustain one or even more drive failures, depending on which drives fail, as long as both drives in a mirrored pair are not lost simultaneously. This capability significantly reduces the risk of data loss compared to other options, making RAID 10 a robust choice for environments where data availability is critical.

In contrast, while RAID 5 offers some level of redundancy through parity data, it can only tolerate the failure of a single drive. If more than one drive fails, data recovery becomes impossible. Snapshots are useful for creating point-in-time copies of data but do not provide continuous data protection or redundancy—they require underlying storage that can fail.
