Here is the latest entry in the physical data destruction market:  MediaVise by Phiston Technologies:

The MediaVise™ is a desktop data sanitation solution standing only 25" tall and 12" wide. When a computer hard drive is "fed" into the MediaVise™, its patent-pending crushing plates deliver over 33,000 pounds of force per square inch to the vulnerable platters and read heads of the drive. In less than a minute, the hard drive is crushed, mangled and rendered unreadable and discharged into a debris collection bin. The entire process is "hands off" and meets NSA specifications for Data Destruction.
