Is this a verifiable claim?

NetApp also claims that its RAID-DP technology is “4,000 times more reliable” compared to conventional RAID-1 systems, in terms of safeguarding disks against failure.

How did NetApp come up with this figure? The News reporter doesn’t say. I would be interested in finding out how much more reliable their RAID-DP is compared to RAID 5, which seems to be the most prevalent raid in the Data Centers we visit. Also, it would be interesting to learn why RAID-DP was released after SATA Disk technology was put into NetApp systems. Was there any linkage between SATA unreliability, as compared with FC disks, and the Release of RAID-DP? Is the RAID 4 that NetApp used to recommend inferior to their RAID-DP? Perhaps the SATA disks are more unreliable, so a dual hot parity disk solution is required? Maybe Keith Brown, NetApp director of technology and strategy, or one of our loyal readers at NetApp can answer these questions for us?

Have a great Holiday weekend !
