Advantages of Perpendicular Recording

After more than ten 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

  • Provides the industry’s highest capacity—up to 750 GB (also 640GB, 500GB, 320GB, 160GB AND 80GB).
  • Ships with the most reliable and proven perpendicular magnetic recording (PMR) technology.
  • Delivers high performance
    - Up to 120-MB/s sustained data rate
    - 2-MB, 8-MB and 16-MB cache buffer options.
  • Environmentally friendly
    - Consumes up to 43 percent less power during idle than previous products, enabling customers to built low-power systems.
    - Meets RoHS requirements.
  • 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.
  • 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
