Characteristics/Advantages

1. RAID 10 is implemented as a striped array whose segments are RAID 1 arrays

2. RAID 10 has the same fault tolerance as RAID level 1

3. RAID 10 has the same overhead for fault-tolerance as mirroring alone

4. High I/O rates are achieved by striping RAID 1 segments

5. Under certain circumstances, RAID 10 array can sustain multiple simultaneous drive failures

6. Excellent solution for sites that would have otherwise gone with RAID 1 but need some additional performance boost

Disadvantages

7. Very expensive / High overhead

8. All drives must move in parallel to proper track lowering sustained performance

9. Very limited scalability at a very high inherent cost

Recommended Applications

Database server requiring high performance and fault tolerance

RAID Level 10 requires a minimum of 4 drives to implement
