StorageMojo � Everything You Know About Disks Is Wrong
I've said it before and I will continue saying so Raid Doesn't work.
Now StorageMojo reports Everything You Know About Disks Is Wrong based on the Usenix Paper
Disk Failures in the Real World: What Does an MTTF of 1,000,000 Hours Mean to You? which summarrizes to the same conclusion.
Further, these results validate the Google File System's central redundancy concept:forget RAID, just replicate the data three times. If I'm an IT architect, the idea that I can spend less money and get higher reliability from simple cluster storage file replication should be very attractive.
Ok I admit.. I've ben preaching put your data on at least 2 places and they claim 3 :)
