   @rysiek volatile storage does get a bit tricky because large SRAMs are very expensive, whereas DRAMs have higher power consumption and requires a more complex controller for doing refreshes. likely wouldn't be too pricey to make 32GB or 64GB with LPDDR2/3 though.

   instantly dropping the data with a button press or tamper alert is super easy in that context though.

     Big question is power. If using flash storage, *something* needs to measure time and then delete the data. That *something* needs to be powered.

     But maybe we can flip the script? Maybe this could be done using *volatile* memory and just enough of energy storage to keep it up for 24h?

     ✨ Power runs out, data goes away! ✨

     Add a tiny bit of read-only storage for template partition table to be automagically copied to the volatile storage the moment it's plugged into a powered device? 🤔

     Idea: thumb drives that retain data for a set amount of time (say, 24h) and then destroy it automagically.

     I want to not have to think about safely deleting the data from the thumbdrive I used to move two files across the hall.

     Surely we could have that technology?
