RAID 10 is indeed synonymous with RAID 1 + 0. This configuration combines the data redundancy features of RAID 1 (mirroring) with the performance improvement aspects of RAID 0 (striping). In this setup, data is first mirrored across pairs of drives, providing a backup if one of those drives fails. Then, the data is striped across multiple mirrored pairs, which enhances read and write performance by allowing concurrent access to multiple drives.

This architecture provides both high availability and increased performance. It effectively safeguards against data loss while enabling quick access to the data due to the striping technique used. Thus, RAID 10 is crucial for systems where both performance and data integrity are important, making RAID 1 + 0 the correct characterization of RAID 10.
