Extreme...?
For a civilian yes.. In other words that card isn't "Military grade"... its "nerd grade"... cause someone in the military can crack it open regardless of what defenses it may have --the sides can be torn apart to allow observation. Then copy the encrypted bit contents,and run it through several algorithms till it comes out clean. Not to mention they can have the pathing systems of the encryption chip analyzed so they can learn how the info was encrypted.. as well as sever the pathing that allows the chip to "burn itself and dump scrambled data in". That in effect would give them unlimited tries.

Also, what person would want a memory card that doesn't work after 10 failed uses, EVER AGAIN?
So.. civilian wise, its an expensive toy for a child/curious person to momentarally mess with till it fries itself. Military wise, its just an irritation.
