I-O Data have given the heads up that they'll be adding a larger 2TB capacity variant to their existing HDJ-UT lineup of USB 3.0-ready external hard drives at the end of this month.

The 2TB model runs dimensions of 46 (W) x 223 (D) x 155 (H) mm with a weight of 1.6Kgs. It features active cooling and can of course be used on standard USB 2.0/1.1 systems as well (albeit, significantly lower speeds).

I-O Data says the unit is capable of transferring data at up to 139MB/sec using a USB 3.0 connection. The 2TB model is expected to show up in Japan at a price of around $315 U.S.
