Barracuda hard drives from Seagate give you the Power of One. One terabyte per disc technology. One drive platform for every capacity need and every desktop storage application. One hard drive qualification effort. One hard drive platform to choose from. One hard drive with trusted performance, reliability, and simplicity to deliver the lowest total cost of ownership.

You no longer need to choose between low power drives, mainstream drives, or performance drives. One hard drive with 7200RPM performance and capacity points from 250GB to 3TB makes it easier than ever to choose the right drive for any need.

No need to choose between low power drives, mainstream drives, or performance drives.
See how it stacks up versus the competition

Seagate Barracuda drives are ideal for nearly any application

Bigger

You get more bang for your buck with 1TB per disc technology. Increasing the capacity per disc means the highest capacity drives like 1TB, 2TB and 3TB become more affordable, needing fewer discs to meet your capacity needs.

Faster

Your drive is up to 45% faster than the last generation thanks to Seagate OptiCache technology. OptiCache technology combines the latest advances in hard drive microprocessors, DRAM, and proprietary caching algorithms resulting in great performance improvements for you.

Simpler

You don't have to worry about the transition to Advanced Format 4K technology with Seagate SmartAlign technology. With SmartAlign, 4K drives look and act just like legacy 512 byte sector hard drives which makes your adoption of Advanced Format simple.

Stronger

You get reliable read/write performance even in tough operating environments with Seagate AcuTrac technology. AcuTrac represents new advanced hard drive technology that can accurately control reading and writing on these "nano-sized" tracks spinning at 7200 RPM, even in high-touch environments, such as an all-in-one PC with loud music booming through the speakers.

Safer

The free DiscWizard software allows you to configure your system to access a 3TB drive, even on legacy PC BIOS systems or Windows XP. It's a safer, more cost-effective solution for installing 3TB hard drives.

Ideal for Any Application

From desktop or all-in-one PCs, to home servers, to PC-based gaming systems and more, Seagate Barracuda drives are ideal for nearly any application. They work great in desktop RAID configurations, as well as in direct-attached external storage devices (DAS) and network-attached storage devices (NAS).

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.
