Eight 2 TB hard drives roundup
The first 2 TB hard drives appeared at the beginning of 2009. Western was the first to launch with the Caviar Green WD20EADS in January, Seagate replying in April with the Barracuda LP. These two drives stood out for their usage of 4 x 500 GB platters and rotation speeds below 7200 rpm: 5900 rpm on the Seagate, with no value given by Western, but approximately 5400 rpm. We carried out our first tests on these drives in July 2009.
Since then, the range has been extended, with all manufacturers now offering products at this capacity. From Hitachi, there’s the 7K2000, a model with 5 x 400 GB platters, but with a rotation speed of 7200 rpm, while the Western Caviar Black and the Seagate Barracuda XT use 500 GB platters. Samsung has up till now made do with a 5400 rpm drive, the SpinPoint F3 which uses 4 platters; a 3 x 667 GB platter drive is planned for September.
Western is also marketing the first 2 TB drives, the WD20EARS, divided into 4 KB sectors, a technology we’ll come back to on page 2. The most recent version (00MVWB0) has 3 x 667 GB platters, against 4 x 500 GB platters for the 00S8B1s and 00J2GB0s.
