    highest storage workload performance efficiencies
  • Reliable access to unstructured data in bulk storage applications
  • 12 Gb/s SAS and SATA 6 Gb/s interfaces in industry-standard formats (512n, 512e
    and 4Kn) for easy integration into replicated and RAID multi-drive storage servers and
  • State-of-the-art cache, on-the-fly error-correction algorithms, super parity and end-to end
    SAS-based data integrity for accurate data storage
  • Industry-leading rotational vibration design helps ensure consistent performance in
    dense multi-drive systems
  • Engineered for 24×7 workloads of 550TB/yr - 10× that of desktop drives
  • Robust performance with dual processors, ramp load technology, top-cover-attached
    motor and humidity sensor for optimum performance in all chassis
  • On-demand PowerBalance™ feature available for lower power/performance in random
    read/write environments
  • Seagate Secure® Self-Encrypting Drive featuring Instant Secure Erase for cost-saving
    drive retirement and secure data-at-rest protection
Best-Fit Applications
