The Model 0300 Jackhammer Hard Drive Shredder from Security Engineered Machinery of Westboro, Massachusetts, destroys hard drives, electronic devices like cell phones, optical media such as CDs, and computer backup tapes. Its special sawtooth, hooked cutters can handle 125 to 500 drives per hour, reducing them to 1 1⁄2-inch shreds. Designed for the office environment, it requires no special wiring. It is mounted on locking swivel casters and operates quietly and cleanly. It accepts hard drives up to one inch thick, and offers multiple safety features. A key is required to operate the machine, and it meets National Security Agency requirements for physical destruction of drives after they have been degaussed.
