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

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 deliver 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
