Thumb drives pose a distinct risk due to their use of flash memory chips. Standard magnetic erasing has no effect on flash-based media.

Micro-shredding: Because the memory chips are so small, they must be shredded into extremely small particles to ensure CDs the silicon is pulverized.

Mechanical Destruction: Employing a heavy-duty press to break the internal circuitry is another method of protection.
