RAID6 - Block-level Striping + Double Distributed Parity
  • Expands on RAID5 by spanning two parity sets across the array and requires a minimum of four drives for implementation
  • RAID6 arrays can sustain two simultaneous drive failures without loss of data
  • Read performance is exceptional like RAID5 however write performance is slightly worse [than RAID5] due to the additional write-stream for the second parity set
  • Double parity generation requires extensive system resources
