The drill press? It certainly does for non-classified media. Classified 
media requires a thorough degaussing optionally followed by physical 
destruction. Incineration is also an option for classified media.

Incineration is also acceptable for flash media.

Repeat statement about how flash-based media are consumables.

And all I -- for some value of "I" which may not be myself -- have to do 
is find a way to recover that key which, depending on [insert everything 
about potential weaknesses in algorithms and schedulers and 
not-really-random number generators here] may not be that difficult. 
Depends on your threat model.

Or you could use RAM-based SSDs instead of flash. Almost instant 
sanitizing when power is removed.
