RAID 10: Very High Reliability combined with High Performance  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 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 |
