Most of us know that just because you hit the delete button on your computer to remove a file from your HDD or external storage doesn't mean the data is actually gone. The data sits on the drive and is simply marked to allow overwriting by the OS.

That means if you have sensitive files you don't want to fall into the wrong hands you have to use special processes for deleting data. Elma Electronic Systems has introduced a new mass storage device that uses erasing techniques that meet ten different military and defense secure erase standards.

The drives also have write protection to prevent accidental overwrite of critical data. The drive has two buttons on the front panel with one for erasing and one for write protect. Each drive has 128GB of storage and is very rugged. The drives sell for $2700 in low quantities.
