I am curious if people actually replace hard drives periodically because

SMART and raid scrubs. However, it makes me wonder when they will die.
What is the best policy in such situations? More importantly, do people
wait for disks to die and then replace or have some ad hoc schedule of
replacing (like every 6mo replace oldest) to keep things safe?
I replace drives when their relocation count hits double digits. In my
limited sample, that's typically after 40,000 hours.

Thanks for the data point. 40K hours means roughly 4.5 years with 24/7.
That is very good. You use enterprise drives? Mine are desktop (and may
be one HGST NAS)
My SMART is perfect except for power on hours. I am going to take it
easy for now as I have a spare (not part of a RAID) just in case
something bad happens.
