So, product idea: A powered "cold storage box" for M.2 SSDs. 2 to 8 M.2 slots. Periodically, an internal computer connects one of the slots, reads every byte, waits for some period of time, then powers off. Maybe shows a little green light next to each drive when the last read was successful. Could be battery-powered.

here's a better idea, buy a mechanical hard disk.

How often does it need to run? If it could be solar powered you could probably avoid a whole bunch of complexity per unit longevity.

How much are you saving vs an always-on ARM board with M.2 slots? Is it worth the pennies?
