Question: On platter drives, when it is time to dispose of them, a degaussing takes care of the data and in most cases erases the factory pre-recorded servo tracks rendering the drive useless.
What does one do to an SSD to get the same data destructive and rendered useless assurances?
EDIT:
Would taking it out of the case an microwaving it do the trick?
Answer: With any device, completely physically destroying it would work. For example, dumping a load of thermite on top, or throwing it into an incinerator. Unfortunately, unlike HDDs, drilling a couple of holes randomly likely won’t work – but if you can locate the flash chips, you can smash those up.
Apart from that, SSDs all (to the best of my knowledge, though it is difficult to confirm without testing) implement the ATA secure erase command (or its SCSI equivalent), which can be sent to cause the firmware to erase all data.
