Just a nice summary of the issues with (in)secure deletion on SSDs. Old, but a good quick reference.
The resistance of data to permanent secure erasure on SSDs indicates to me that the best way to securely use a SSD is to use full-disk encryption. Then when you need to get rid of the SSD, you just dispose of it in the same way you dispose of other electronics.
The extent of my knowledge on safely wiping data from SSDs is that this patent exists: https://patents.google.com/patent/US20170050190A1/en.
Lmao this patent is basically “throw it in a blender.”
With chunks of ice. Not to make an SSD smoothie, just so you don’t breath in the dust.
