RAID 10

RAID 10 configuration

RAID 10 is a striped (RAID 0) array whose segments are mirrored (RAID 1). This is a popular RAID level for environments where high performance and security are required. In terms of performance, it is similar to RAID 0+1. However, it has superior fault tolerance and rebuild performance.RAID 10

Minimum number of drives required: 4

Performance: Very High

Redundancy: Very High

Efficiency: Low

Advantages:

  • Extremely high fault tolerance – under certain circumstances, this RAID level can sustain multiple simultaneous drive failures
  • Very high performance
  • Faster rebuild performance than 0+1

Disadvantages:

  • Very expensive
  • High overhead
  • Limited scalability
