How many kb does it take to incriminate someone?

How many mb can you fit onto one square mm of a modern drive?

Besides, as noted before, after a simple overwrite of data (or few if you're
paranoid), then data recovery requries specialised equipment and serious dollarbucks. 

5 Minutes with a blowtorch is probably easier,
cheaper and more effective than grinding to dust.
(this is totally speculation of course, I'm not that paranoid :)
