I have a question about SSD respecting security.  Recently I have been
investigating sanitizing these devices, together with 'smart-phones, tablets
and pads which use flash memory persistent storage. Not to mention the
ubiquitous USB 'memory stick'.  I have come to the rather unsettling
conclusion that it is effectively impossible to 'sanitize' these things short
of complete and utter physical destruction, preferably by incineration.  Is
this in fact the case?
