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 yearly operation (24x7x365) within the most demanding storage environments, and are backed with a 5 year limited warranty.
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.
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.
Dynamic fly height technology
Each read-write head’s fly height is adjusted in real time to ensure consistent performance for reduced errors and optimized reliability.
