I-O Data Japan expanded its HDCA-UT series of external HDDs with the HDCA-UT4.0K, which packs 4 TB of unformatted capacity, and USB 3.0 SuperSpeed interface. Like other members in its series, the HDCA-UT4.0K is designed to work as a self-contained DVR with compatible TVs, to record high-definition TV programs. It can be concealed behind TVs by clinging it onto its VESA wall-mount. The drive features a power-management mode that powers itself on/off along with the TV. Measuring 39 x 185 x 120 mm, the HDCA-UT4.0K weighs 1.1 kg. Slated for late October, it is priced at 38,850 JPY (US $496).
