Kingston Digital has announced what it claims is the world's highest capacity USB flash drive, which comes in both 1 terabyte (TB) and 2 TB flavors. Both probably much bigger than you could ever really need. The Kingston DataTraveler Ultimate Generation Terabyte (GT) isn't exactly small. As you can tell in the picture above, where the actual body of the drive dwarfs the USB part, it's a bit bigger than, say, your regular issue SanDisk. But that's still smaller than Amazon's new portable storage device, the Seagate Duet, which can only (a relative term here) hold 1 TB.
