One option they don't mention: Thermite. Seriously, if you physically melt the chips, they're not going to retain any information.

- chinathrow 10y agoIndeed. http://frank.geekheim.de/?p=2423 http://frank.geekheim.de/?p=2423 (German) https://www.youtube.com/watch?v=k-ckechIqW0 https://www.youtube.com/watch?v=k-ckechIqW0
- kijin 10y agoThermite sounds a bit excessive for a typical home or office. How about baking in an oven or roasting on a grill? Is modern flash memory fragile enough to be destroyed irreversibly at 230C/450F?
- phire 10y agoMaybe. They have to be rated to survive those temperatures for short periods of time during reflow soldering. Apparently flash memory is rated to last a minimum of 10 hours baking at 125c, or 360 hours at 85c. The decay is exponential, so in theory 30-60min at 230c should do a lot more damage. But I'm not sure you should rely on it, that 10 hours @ 125c number is for when the bit-errors exceed the capabilities of the ECC. The data will be partially recoverable for much longer. Or you might have some flash which does a lot better than the minimum spec. https://www.eeweb.com/blog/eli_tiomkin/industrial-temperature-and-nand-flash-in-ssd-products https://www.eeweb.com/blog/eli_tiomkin/industrial-temperatur...
- kijin 10y agoHow about microwave? Powerful charges at every exposed terminal looks like a nice way to fry some chips. Maybe submerge the whole PCB in a bowl of salt water to prevent sparks flying everywhere...
