RAID LEVELS
RAID LEVEL 10: RAID Level 10 | RAID 10 Advantages and Disadvantages
RAID Level 10 requires a minimum of 4 drives to implement
Characteristics & 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
- RAID level 10 can be very expensive / High overhead
- All drives must move in parallel to proper track lowering sustained performance
- Very limited scalability at a very high inherent cost
Recommended Applications
- Database server requiring high performance and fault tolerance
