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.Īll Ultrastar hard drives are extensively tested across a variety of popular OEM storage systems, SATA controllers, and host bus adapters to ensure ease of integration for a plug and play solution. Ultrastar drives feature a dual-stage actuator head positioning system for a high degree of accuracy. And now on its 5th generation design, HelioSeal technology is field-tested and proven to deliver high capacity, reliability, and power efficiency you can trust.Įnhanced 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 drives in high-vibration environments.Įach read-write head's fly height is adjusted in real time to ensure consistent performance for reduced errors and optimized reliability.
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.įeatured in over 30 million Western Digital hard drives shipped, HelioSeal technology allows for higher capacities and lower power on large storage arrays.
