Douglas Smith has a post up over at the new Network Instruments blog:

In a nutshell, the study states that drive failure rates are between 2-13% per year. We have seen other studies that state average failure rates are around 5% per year. Keep in mind that these rates are for average use (studies include data centers and user systems). Hard drive manufacturers would have you believe the average rate of failure (MTBF) is over 1.5 million hours. This equates to roughly over 171 years of constant service before problems. A 5% failure rate translates to 100% failure in 20 years, a far cry from 171 years…

We’ve enjoyed working with the people over at Network Instruments (they acquired our LanHound customer base) and they seem to take their software work seriously. And it looks like they have a good blog effort starting.
