Protecting data stored on a solid state drive

A computer system, comprising:

• a memory;
• a processor coupled to the memory;
• and
• a solid state drive (SSD) coupled to the processor and comprising a controller and a plurality of non-volatile memories, the controller configured to prevent data that is stored on the SSD from being located and read, the controller operable for:
• mapping a logical address to a physical address in the SSD and writing data to a first non-volatile memory location in the SSD identified by the physical address;
• storing, in a second non-volatile memory location in the SSD, first metadata comprising a map from the logical address to the physical address for the first non-volatile memory location where the data is stored;
• and
• with the data stored at the first non-volatile memory location, erasing the first metadata including the map from the second non-volatile memory location.

A solid state drive (SSD), comprising:

• a plurality of non-volatile storage elements;
• and
• a controller coupled to the storage elements;
• the controller operable to execute operations that prevent data that is stored on the SSD from being located and read, the operations comprising:
• mapping a logical address to a physical address in the SSD and writing data to a location in a non-volatile storage element in the SSD identified by the physical address;
• storing, in a first non-volatile storage location in the SSD, first metadata comprising a map from the logical address to the physical address for the location in the non-volatile storage element where the data is stored;
• and
• with the data stored at the location identified by the physical address, erasing the first metadata including the map from the first non-volatile storage location.
