IT'S THE FLASH DRIVE'S equivalent of the black box.

Beat it up, freeze it, or burn it — the data inside remains unharmed.

Livermore-based Memtech has made its mark by developing flash memory drives that can stand up to the most rugged of conditions.

"The key to our products is making sure none of the data gets lost, regardless of the conditions," said Larry Schuster, vice president of Memtech. "You can literally run over the drives with a car, and they will manage just fine."

A flash memory card is a device that plugs into a computer and functions as a portable storage device. Some of Memtech's drives can store up to 60 gigabytes of information. The drives start at about $1,000.
