Seagate Barracuda Hard Drives
The Power of One
Barracuda hard drives from Seagate give you with 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.
The Size and Performance You Want
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.
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.
No-Hassle Transition to 4K Technology
You don't have 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.
Maximizes Hard Drive Storage Densities
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.
Proven Quality and Performance
Barracuda has become the world's most popular family of hard drives with consistent quality and performance-enhancing innovations and features like native command queuing and perpendicular recording. Additionally, the legendary family of Barracuda desktop hard drives is produced using the most sophisticated manufacturing process in the industry, with a focus on environmental stewardship.
Go Beyond 2TB with DiscWizard Software
The sure way to get native access to hard drives bigger than 2TB is to adopt the new BIOS standard called UEFI. If you're not there yet, Seagate has an alternative. You can now use Barracuda 3TB hard drives even using legacy PC BIOS, or Windows XP with free DiscWizard software. 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.
Green Where it Counts
Barracuda 1TB-per-disk hard drives now have advanced power modes to save more energy while in idle states--without sacrificing performance. Produced using the most sophisticated manufacturing process in the industry, with a focus on environmental stewardship, Barracuda drives comply with the RoHS directive on hazardous materials and voluntarily restrict halogen compounds. Plus, 70% or more of the materials used to build Barracuda drives are recyclable
