“physically destroys the NAND chip to ensure zero data residue and prevent any form of data recovery.” and "You need to have the drive plugged into the USB port of a PC or Mac to initiate it."
It's not much more expensive to have symmetric encryption (to prevent any possibility of data residue) in the drive where pushing the button zeroes the key and you can use it again after formatting it. It's more secure.
