As disk drive densities continue to increase, and companies adopt SATA disk drives to reduce storage costs, data loss due to concurrent disk drive failure and error in a RAID group has become a growing risk. Single-parity RAID 5 does not protect against such double-failure events. While RAID 1+0 and conventional RAID 6 do provide sufficient protection, each has serious drawbacks - RAID 1+0 requires nearly twice the number of disk drives, and conventional RAID 6 slows performance significantly. The solution is NetApp RAID-DP, an advanced RAID 6 technology.
