Would an EMP destroy a flash drive, or memory card?

Only if the flash drive is connected to a computer at the time.

Yes. EMP pulse generates a dynamic electromagnetic field that induces currents in closed circuits. Even if the card is not in the reader, there are closed circuits in it and these circuits get fried by the pulse.

Thanks.

That sucks. I wanted to keep some porn on it for when civilization rebuilds itself sometime in the future, following the end of the world.

Who knows. If the electric grid goes down you won't have a computer to run one on anyway.

It's more likely that the hundreds, thousands, or probably tens of thousands of enemy cells (Cuban, Venezuelan, Iranian, Russian, Mexican, etc.) in this country would commit sabotage against the power grid. They won't need an electromagnetic pulse.

Not necessarily if you put them underground.
