This post and many other sources mention if an SSD is unpowered, the data may in some cases last mere months before bits start to flip: https://www.reddit.com/r/DataHoarder/comments/ba8o0b/will_ssd_lose_data_if_left_unpowered_for_extended/ I'm interested in this use case for an off-site backup that is unpowered.
Now that left me wondering, to do a best effort approach of mostly preventing that outside of the usual other risks like controller failure and so on, what is a likely sufficient strategy? Is it enough to simply plug it into a machine and mount it for a few minutes, twice a year? Would that "restore" whatever gradually less powered bit state all of the cells on there might have had? Or do I need to rewrite the data that is already on there, or do something else specific?
Summed up, I don't understand enough about SSDs to understand what's likely a somewhat sufficient strategy here. And I was curious if somebody here might know how this works.
