Remember the day you drooled all over your keyboard when Hitachi introduced a 1TB internal hard drive? Yeah, like a year and a half ago? The outfit's most recent HDD announcement isn't likely to have nearly the same effect, but those who skipped the first-gen version in order to get a more refined product the second go 'round will surely be delighted. Today marks the debut of the 1TB Deskstar 7K1000.B, which goes down as "the world's most energy-efficient 7,200RPM one-terabyte hard drive." Said drive features a new three-disk design which improves idle power consumption up to 43% over its 1TB predecessor, but unfortunately, there's no telling how long you'll have to wait to actually buy this currently unpriced overlord of storage.
