How do I wipe a modern SSD to prevent data recovery? (self.asklemmy)

I understand traditional methods don’t work with modern SSD, anyone knows any good way to do it?

If you want to keep/sell the drive...

Fill up the rest of the usable space
Encrypt the drive
Throw away the encryption key/password
Hard format (writing zeroes to every bit, sorry if that's the wrong term

Is that the best strategy? Or is anything outside of 2 and 3 redundant?

You can’t fill the drive. The drive decides when to use its buffered free storage blocks. It’s at the hardware level and only the Secure Erase command will clear it.

Right, I read some more of the comments and realized that's what some of the "unreported space" is used for. Makes sense, thanks!

You fill up the usable space. Or the visible space. No one will disamble the device and read from the raw storage.

Then why do that when you can do a secure erase in seconds?
