About the Seagate Barracuda 1TB

The Seagate ST1000DM003 Barracuda 1TB SATA hard drive gives you the Power of One, one hard drive platform for every desktop storage application and one drive with trusted performance, reliability and simplicity and capacity. This 1TB Seagate Barracuda hard drive also features Seagates '1TB-per-disc' technology that packs 340,000 hard drive tracks into the width of a single inch, this means that, when reading and writing data, the read/write head needs to accurately follow a track that is a mere 75 nanometers wide. That's about 500 times smaller than the full stop at the end of this sentence.
