Hitachi's 1TB hard disk drive indisputably represents a milestone in desktop storage, as the 1GB landmark in desktops was achieved back in 1995. As with many top-of-the-line purchases, end-users will have to pay a significant premium for 1TB on a single drive. Currently Hitachi Deskstar 7K1000 hard disk drives are available in Japan for Â¥51 500 - Â¥55980 ($433 - $470), much higher compared to Seagate Barracuda 750GB, which retails for Â¥29400 - Â¥39660 ($247 - $333) in Tokyo. The recommended price of the 1TB drive from Hitachi for the U.S. is $399, whereas Seagate's 750GB product costs starting from $249 in the country.
