Hitachi's latest announcement in the mass storage arena isn't breaking any capacity barriers, but is certainly worth nothing. The company announced today their second generation of 1TB hard drives with the release of the Deskstar 7K1000.B. Hitachi is playing up how "green" the drive is in terms of power consumption, claiming it uses up to 43% less power than the former 1000B Deskstars and is actually the most energy-efficient model on the market. The disks use a three-platter design, something that many early 1TB drives often lacked.
Power consumption is a critical considering of modern hardware and everyone except GPU manufacturers seem to have this figured out. You can read more about Hitachi's new drives in the full press release in the comments section.
