Google Paper on Hard Disk Failures

Google technicians have been monitoring some 100,000 disk drives over 5 year period and the have come up with some finding which they claimed sheds new lights on how some of the technologies behind disk drives work. Excerpts from the papers:Our analysis identified several parameters from the drive’s self monitoring facility (SMART) that correlate highly with failures. Despite this high correlation, we conclude that models based on SMART parameters alone are unlikely to be useful for predicting individual drive failures. Surprisingly, we found that temperature and activity levels were much less correlated with drive failures than previously reported.
