Any generalizations for consumer drives, any brand and model, mainly desktop but not only?
The Backblaze info says they use standard drives, even drives sold as basic external drives. If I recall, maybe also Google frequently uses standard drives. These run 24/7, last a few years, or more. If I take the warranty period as an indication, assume 24/7, and add some extra, 3 year drives are ~30K hours. But then, Backblaze's >94% survival rate after 3 years, excluding Seagate, shows it can be much more than that.
So I wonder when one should retire drives based on hours, and whether offline/nearline HDD storage can be good for 10+ years.
