in my exp sas disks that are still working after 25k hours on without any issues - are pretty much immortal until components wear out.

Most wear is created when system is rebooted, and started up; so at certain point if system is always online the disks are immortal.

But 25K hours is less than three years. Most enterprise drives have a 5 year warranty so I'd say the minimum is at least that - 43K hours.

Many companies run their servers beyond the warranty though so around 8 years or so is not unusual to see. That's 70K hours.

It's an admirable attempt at summarising complex data on HDD reliability, but their methodology really pales in comparison to BackBlaze's analyses. Annualised failure rate (normalised by drive-years).
