Advantages : RAID 10 is implemented as a striped array whose segments are RAID 1 arrays. RAID 10 has the same fault tolerance as RAID level 1. RAID 10 has the same overhead for fault-tolerance as mirroring alone. High I/O rates are achieved by striping RAID 1 segments. Under certain circumstances, RAID 10 array can sustain multiple simultaneous drive failures. Excellent solution for sites that would have otherwise gone with RAID 1 but need some additional performance boost.

Disadvantages : Expensive / High overhead. (compared to Raid 1.) All drives must move in parallel to proper track lowering sustained performance. Very limited scalability.

Recommended Use : Database server requiring high performance and fault tolerance.
