I've had 6 or so USB disks fail inexplicably. Sounds like the proposal is a heater and a timer that are embedded on the stick. That doesn't sound like high cost. I suspect theres a timer and thermometer already on the sticks, that leaves just a heater, which are super cheap.

Failing inexplicably does not mean that it failed because of the issue talked about here. It could as well be bad contacts or soldering whiskers. I'd prefer a USB stick that does not fail too, but in fact, I have never had any fail on me so I don't know the prevalence, and know even less which parts come from this specific issue. Also, if your USB drive starts having a heating element, you need to trust it to not fry everything due to a regulation failure in badly designed units that fail closed. I also doubt a process of heating "at 250 degrees for hours" could be done at 50°. Even of it could, it would literally take days at a time.
