Or leave the drive on all the time in an enclosure that keeps the nand cool (near room temperature).

Any decent SSD will background rewrite itself over time at an appropriate rate. Detecting that it needs to do so after 2 years in storage seems trickier to get right (no realtime clock) and trickier to test.

I’d be curious to know how quickly the drives in the article “heal” themselves if left plugged in. There’s nothing wrong with the hardware, even if they did lose a few sectors.

If you really want to create a correct protocol, you can accelerate nand aging by sticking them in an oven at an appropriate temperature. (Aging speedup vs temperature curves are available for most nand devices.)
