Alt MPN: HUH728080AL5204

Highlights

  • Industry-leading 8TB capacity in a standard 3.5-inch form factor
  • Industry’s best Idle and Active power efficiency (Watts/TB).
  • Reliable, field-proven, 2nd generation HelioSeal™ process and 7Stac™ design.
  • Rebuild Assist mode shrinks RAID recovery time and nearly eliminates system performance degradation during rebuild.
  • Double the capacity.
  • 60% more power efficient (Watts/TB).
  • 1.5X to 3X faster random write performance thanks to media cache architecture.

    • 19% faster sequential read/write performance

Applications/Environments

  • Enterprise and data center applications where capacity density and power efficiency are paramount
  • Cloud and hyperscale storage

    • Massive scale-out (MSO), high-density data centers

  • Distributed file systems like Ceph™ and Hadoop® to support Big Data Analytics
  • RAID arrays
  • Video surveillance and content distribution
