I've had Hitachi Deskstar (49000 hours run 24x7) and Travelstar (47000
hours IIRC in a Lenovo laptop) disks last a lot longer than that with no
special handling or environment.

However, both machines ran smartd so and I read the weekly reports, so
knew more or less exactly when they were about to fail. In both cases
that were replaced quite close to EOL and without data loss.

As a result I highly recommend running smartd on any system using HDD or
SSD drives as their primary storage, i.e. anything that doesn't use an SD
card as its primary storage, and keeping at least two generations of
offline backups. Currently I'm using WD Elements USB drives for my
backups.
