Here's the myth that fails more disposal programs than any other: running retired SSDs through a degausser. Degaussers destroy data by eliminating magnetic fields — and flash memory doesn't have any. The data on a degaussed SSD is completely intact.
Software overwrites aren't reliable either. SSDs use wear leveling and overprovisioned cells, which means there are regions of storage that an overwrite tool never touches — no matter how many passes it runs.
What actually works, per NIST SP 800-88: firmware sanitize and block-erase commands with verification, cryptographic erase where encryption was enforced, or physical destruction at a particle size appropriate for flash chips.
If your process predates your SSD fleet, the guide's media-by-media decision table will catch it in five minutes.
