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.
*as compared to 55TB/yr workload rating on desktop-class drives
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.
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.
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.
