I have a 1TB QLC SSD that I use as an occasional backup. Will do a cleanup later but for now it's almost full. I sync it every 3-4 months, then it goes into cold mobile storage (my backpack).
I remember read something like you should plug these things into an on computer every once in a while because the data is held via electrical charge and they slowly lose that charge so you essentially have to recharge them.

1) Is that true or bullshit? If true,
2) What exactly do I have to do to 'refresh' the charge on them? Is just plugging them in to an on computer enough, or do I actually have to interact with the content somehow. Is a full virus scan enough, or something more in-depth?
3) How long does it need this charge and how often? I imagine QLC would need it more often/longer than TLC because it's more precarious?
