Tom's Hardware: "The race to terabyte capacity points in the 3.5" desktop space ended almost one and a half years ago. Hitachi was first to market with its Deskstar 7K1000. Samsung had announced its terabyte drive rather early, but WD made it to the shelves next with its Green Power Caviar GP 1 TB drive, followed by Seagate's Barracuda 7200.11, and then Samsung's Spinpoint F1.
Although Seagate is about to release its next product generation, which will store a massive 1.5 TB of data, 1 TB drives will soon become the norm for performance desktops, making this segment extremely attractive. That was reason enough for Hitachi and Western Digital to release completely revised products, which aim at claiming the performance and efficiency crowns. Enter Hitachi's Deskstar 7K1000.B and the Western Digital Caviar Black 1 TB."
