What if the destruction fails, or isn’t thorough. Much harder to retrieve information from a partial block of memory if it has also been overwritten with garbage to erase it. Redundancy is essential to security.
A device like that isn’t putting enough voltage into it to “melt” it. It you want it that well destroyed you’re going to need a high temperature incinerator with a good filter since it’s not safe to breath the smoke it will create. Or at the very least a heating element inside it, but then you need layers of heat protection so it doesn’t catch everything around it on fire or burn the person pushing the button.
This isn’t that. This is meant to destroy the data at a moment’s notice with the push of a button. Problem is that it has to be plugged in to do it, which in my mind is defeating the purpose.

I mean, you could probably pick two strategic pins and fry the wells… You might have to do a few of them to make sure that your hit every bank. If you blow through the insulation between them, I can’t imagine any method could recover the data. And it shouldn’t take much current
The liquid thing was just because… You know, solid state drive

Yeah, but again, that requires precise destruction in a cheap chip while making sure both not to do it accidentally and making sure it’s successful afterwards. With redundancy, if one thing fails, there’s something else to do the job. Most corporations have abandoned this idea in exchange for short term profit and planned obsolescence. But it’s actually super important in real security.

But like… You could just make it physical. Put a couple extra leads on the PCB, charge the capacitor, and let the button close the circuit mechanically. You might have to do a couple tests, but that’s better than having storage with a delete button on it
What does a delete button add? It’ll take minutes. Might as well put an e-stop button on your desk that connects to your computer by USB
It’s basically security theatre
