    I think it depends of the usage. In the references, the usage is
for disks permanently installed in a computer. The story is different
for backup devices:

    I've read that SSDs loose their data when not used and one needs to
power them from time to time to refresh the data.

    Instead, the ageing of rust spinning disks mostly happens when they
are used, though they could also be degraded by bad storage condidions:
excessive temperature or humidity, and (why not?) vibrations. Looks like
a bad idea to keep them in the fridge!
