HDDs http://www.pcworld.com/article/128400/hitachi_introduces_1terabyte_hard_drive.html Hitachi Introduces 1-Terabyte Hard Drive Colossal storage reaches new milestone with a drive that holds 1000 gigabytes. Melissa J. Perenson, PC World Jan 5, 2007 1:00 pm Hitachi Global Storage Technologies is first to the mat with an announcement of a 1-terabyte hard disk drive. Industry analysts widely expected a 1TB drive to ship sometime in 2007; Hitachi grabbed a head start on the competition by announcing its drive today, just before the largest U.S. consumer electronics show starts next week.
