| 1One gigabyte, or GB, equals one billion bytes and one terabyte, or TB, equals one trillion bytes when referring to hard drive capacity.2Seagate ships this drive in both 4K- and 512-byte sectors. SmartAlign technology is included on 4K sector drives. Both drives are functionally and physically equivalent. | |||||||
Reliable Performance Seagate Barracuda delivers every capacity point from 250GB to 3TB on full 7200-RPM, SATA 6Gb/s platform and includes a host of refined technologies to further boost performance. Seagate OptiCache technology further exploits big cache sizes and improved microprocessor capabilities, helping boost overall performance by as much as 45% over previous generation.
Green where it counts Barracuda desktop drives are produced using the most sophisticated manufacturing process in the industry, with a focus on environmental stewardship. Compliant with the RoHS and using less power, these hard drives not only save the world but also save your cost–without sacrificing performance.
No-hassle transition to 4K sectors Are you worried about moving to Advanced Format 4K sector technology? You don’t have to be with Barracuda drives. Seagate SmartAlign technology makes this transition a snap: no utilities to run, and no extra integration steps to take up your time.
