That is why I Ilisted the unpowered/ unplugged. there are white papers on ssd data loss when it is disconnected from mobo and stored. The lack of trickle power allows decay in the mem cells simce they are just packed charges, and heat accelerates that loss. They said in as little as a week in a hot room it will have started bit rot. And in some cases a few months in a hot space (say 40 degrees in summer heat we have) and data is gone.

Applying power by itself doesn't keep SSDs from degrading like DRAM though. It's up to the manufacturer to design scrubbing into the controller to correct errors on infrequently accessed data before it's too far gone.
