NVMe Sanitize
An NVMe administrative operation that asks the device to make user data inaccessible using controller-defined sanitization methods and completion semantics.
NVMe Sanitize moves the operation below the file-system layer instead of asking software to overwrite host-visible blocks one by one. Depending on device capabilities, sanitization can involve methods such as block erase, overwrite or cryptographic erase.
Acceptance of the command is not the same as confirmed completion. Status and result information need to be checked, and the selected method should be evaluated against the device's actual media architecture rather than assumed to cover every physical location.
That is why Cryptographic Erase, the TRIM Command, and SSD and NVMe Media Sanitization and Cryptographic Erase describe different guarantees.
