The New Gold Standard

The secret ingredient in our WD Gold product line, Ultrastar hard drives feature up to 10 times the workload rating

of desktop drives and employ advanced technologies for enterprise-class reliability, power efficiency and performance.

Designed from the ground up to be an ultra-robust storage device, Ultrastar drives are the perfect solution for your

business.

High workload rating

Delivering dependable performance to any storage environment, Ultrastar hard drives are designed with a workload rating

up to 550TB per year, up to 10 times the rating for desktop drives. Ultrastar drives employ advanced

technologies for enterprise-class reliability, power efficiency and performance.

Enterprise-class storage to rely on

With up to 2.5 million hours MTBF, Ultrastar hard drives deliver reliability and durability, are built for year

operation (24x7x365) within the most demanding storage environments, and are backed with a 5 year limited warranty.

HelioSeal Technology

Featured in over 30 million Western Digital hard drives shipped, HelioSeal technology (on 10TB drives and above) allows

for higher capacities and less turbulence on large storage arrays. And now on its 5th generation design, HelioSeal

technology is field-tested and proven to delivery high capacity, reliability, and power efficiency you can trust.

 

Product Features

  • Vibration Protection
    Enhanced Rotational Vibration Safeguard (RVS) technology uses sophisticated electronics to monitor the drive and
    correct linear and rotational vibrations in real time for improved performance versus traditional desktop drive in high
    vibration environments.
  • Dual-stage Actuator Technology
    Ultrastar drives feature a dual-stage actuator head positioning system for a high degree of accuracy. The primary
    stage provides course displacement while the secondary stage uses piezoelectric motion to fine tune the head
    positioning to a higher degree of precision.
  • Built on a proven design, part of a complete portfolio
    The Ultrastar SATA Series is a subset of a broad line-up of Ultrastar data center hard drives. The complete
    portfolio offers SAS and SATA models and a variety of data encryption options.
