One of the many data sanitization methods used to securely  and efficiently purge all stored data from the Flash storage device is AFSSI-5020. Defined in the Air Force System Security Instruction 5020 by the United States Air Force (USAF) this method mandates the destructive sequence below to overwrite existing information on a hard drive, SSD, Flash card or other storage device.

The AFSSI-5020 data sanitization method is defined to be implemented in the following way:

  • Pass 1: Formats a drive with all zeros
  • Pass 2: Erases fully all data
  • Pass 3: Programs a random character and verifies the write

Erasing and re-writing a Solid State Drive using the AFSSI-5020 data sanitization method will prevent all software and hardware based file recovery methods from re-creating previously stored information from the drive.

Most data destruction implementations support multiple data sanitization methods in addition to AFSSI-5020. Fortasa Memory Systems Military SSDs incorporate purge sequences that adhere to multiple standards.
