Seagate BarraCuda 7200.12 Hard Drives

The world’s most proven and established desktop family, and the industry’s first 3.5-inch hard drive to utilize perpendicular recording technology

The Seagate Advantage

By now the world knows that Seagate Barracuda 7200 drives, from the world’s premier storage provider, deliver years of reliable service and high performance. This is a product family that has been strengthened and refined over 12 generations. It embodies the highest levels of reliability, performance and capacity. And this latest generation is a leader in environmentally friendly storage.

The drive is available in capacities of 1 TB and 750 GB with 32-MB cache, 500 GB and 320 GB with 16-MB cache, and 250 GB and 160 GB with 8-MB cache. The Barracuda 7200.12 drive is an ideal choice for workstations, desktop RAID, gaming PCs, high-end PCs, mainstream PCs and USB/ FireWire/eSATA external storage.

Advantages of Perpendicular Recording

After years of pioneering research at Seagate, perpendicular recording is now a proven technology. It increases capacity and dependability by storing data vertically, rather than horizontally. And vertically stored data bits mean increased data density—which means higher performance to increase productivity.

   Key Features and Benefits

  • Sustainable technology for a green world:
    - Typically 70 percent or more of the materials used to build the drive is recycled.
    - Complies with the RoHS directive and several non-regulatory restrictions.
  • 12th generation of the world’s most popular desktop hard drive.
  • Ships with the most reliable and proven perpendicular magnetic recording technology.
  • Delivers high performance:
    - 125-MB/s maximum sustained data rate
    - Up to 3-Gb/s instantaneous burst
    - 32-MB cache on 1-TB and 750-GB drives, 16-MB cache on 500-GB and 320-GB drives, 8-MB cache on 250-GB and 160-GB drives
  • Leverages best combination of technology (aerial density, PMR) and proven components for volume availability
  • Best-in-class environmental specifications and reliability features.
  • Adaptive Fly Height offers consistent read/write performance from the beginning to the end of your computing workload.
  • Clean Sweep automatically calibrates the drive.
  • Enhanced G-Force Protection defends against handling damage.
  • Seagate SoftSonic motor enables ultra-quiet operation.

   Key Applications

  • Workstations
  • Desktop RAID
  • Gaming PCs
  • High-End PCs
  • Mainstream PCs
  • USB/FireWire/eSATA Personal External Storage
