[ale] Data not safe on ssds

[Jim Kinney]

A colleague did a funded research project a while back on the data
retention and retrieval methods for erased media. Erasing methods
included government high security methods (bazillion writes of
specialized fields, etc). According to him, SSDs can't be erased fully
by any current technology. The only acceptable way to ensure data
destruction is to grind the chips to dust and incinerate the dust.
