Drive maker LaCie has announced an expansion of its line of Thunderbolt-supporting peripherals on the eve of the annual Consumer Electronics Show (CES) in Las Vegas. In addition to its existing Little Big Disk Thunderbolt drive, the company will be adding a 2Big dual-disk model as well as an eSATA hub that lets users connect two eSATA external hard drives, and offers the possibility of daisy-chaining more at full eSATA 3Gb per second speeds.
