"draws a few

NDAs, probably the same you signed too...
Still: (Most) SD cards are _not_ a reliable, long term storage medium.
IIRC that colleague talked about special "industrial grade" SD cards.
They are guaranteed to be robust and reliable as old fashined NOR
Flash. But they are expensive and have less capacity.

Unfortunately
reading the contents of a cell draws a few electrons of
its charge.
I'd be interested in references for that
