US hardware manufacturers, Seagate, have begun shipping the world’s slimmest portable external hard drive. At just 9mm thick, the 320 GB GoFlex Slim Drive is a little thicker than a pencil.

Initially unveiled at the 2011 Consumer Electronics Show in Las Vegas, the drive can be used with Mac OS or PC, and will go on sale for $100 US dollars.

“The continued growth of personal digital media stores, our increasingly mobile lifestyles and the continued proliferation of mobile devices are driving the demand for slimmer, more portable storage solutions,” said Patrick Connolly, vice president and general manager of Retail at Seagate.

“Netbooks and slim laptops are great for consuming media, but are limited when it comes to creating and storing high–definition films and photos. With the benefit of using Seagate’s Momentus® Thin drive, the 9mm GoFlex® Slim ultra–portable hard drive breaks through these boundaries—delivering a beautiful, ultra–slim, lightweight storage solution to complement existing mobile computing devices so they can enjoy even more of the content they love, anywhere they want.”
