RAID Level 10 requires a minimum of 4 drives to implement

Featured Product

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

Recommended Applications

  • Database server requiring high performance and fault tolerance
