So I learned that if a MicroSD card gets snapped in half, its unrecoverable.

Okay, so suppose you were in war, and enemy soldiers were about to raid you. You just snap the cards in half and the data is un-recoverable, right?

    As long as the silicon got snapped and not just the softer plastic around the silicon.

    If it’s actually important data that a nation state would want, most of the data could still be read off with an electron microscope.

        Your best bet would be to shred the data multiple times (for example with the shred command) and then break the card physically. But shredding takes time so I guess that’s not very applicable to your case.

        If you have a lighter, you also can try to melt the SD card’s insides. That should be impossible to recover.

        In any case, you should keep it encrypted all the time and only decrypt it on the fly. For example with LUKS2.

        Are your teeth able to do significant damage? You can of course dent the plastic shell, but the inside is protected by harder things.
