Imation announced Wednesday it's begun selling a new 4GB version of its Micro Hard Drive.
The $189 product has a padlock-shaped design; its USB connector is a loop that can be clipped to objects such as key chains. It uses a 0.85-inch hard drive from Toshiba and works with Windows, Mac OS X and Linux.
Imation introduced its $159 2GB version of the product in the summer. The 4GB version will be on display at the Consumer Electronics Show's Innovations Plus exhibit at the Sands Expo and Convention Center next week in Las Vegas.
The drive comes with synchronization software and protects all files with 128-bit encryption, Imation said.
