You are retiring a cloud-hosted solid-state drive (SSD) array that stored controlled unclassified information (CUI). According to NIST SP 800-88 Rev.1, which disposal action provides purge-level sanitization while still allowing the provider to reuse the hardware?

  • Execute a single overwrite pass of all logical blocks with pseudorandom data.

  • Submit the SSDs for mechanical shredding into 2 mm particles.

  • Expose the SSDs to a Type I degausser with a 7,000-gauss magnetic field.

  • Invoke the drive's built-in cryptographic erase function to delete and re-generate its encryption key.
