Samsung sees portable storage as the next big thing. Expecting teens to be carrying around buckets of HD movie files and anthologies of digital music, the company has launched a rugged series of external HDDs that the kids of today can drop and cover in fizzy pop to their heart's delight.

The range consists of 1.8-inch, 2.5-inch and 3.5-inch attractively designed units and those launched at CES 2010 are the two larger sizes - the G2 Portable in 250/320/500/640GB and G3 Station at 1/1.5/2TB densities.

The G3 features a smart power mode where the computer can switch it off, if not in use, and it also runs at 95% less power consumption than standard units.

They're out in the next couple of weeks and the top-end models of each category will come in at $199.
