Which RAID configuration is a combination of RAID 1 and RAID 0, also called mirrored striping?

Explanation:
Mirrored striping combines redundancy and performance by first duplicating data (mirroring) and then spreading those duplicates across disks (striping). This is what RAID 10 does: data is written to mirrored pairs, and those pairs are striped across multiple disks. With four disks, you’d have two mirrored sets, and the data would be written in stripes across those sets. This provides faster reads because multiple disks can be read in parallel, and it also offers fault tolerance since a single disk failure in each mirror pair won’t cause data loss. If the same mirror pair loses both disks, you’d lose that data, but overall resilience is higher than with simple striping. Parity-based options or plain striping do not combine mirroring with striping, which is why RAID 10 is the correct choice.
