Drive to endure.
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 choice for your business.
Best-fit Applications
Ultrastar Advantage
The Ultrastar family delivers a long-standing tradition of reliability leadership with MTBF ratings of at least 2M hours and a 5-year limited warranty. Ultrastar quality, capacity, power efficiency, and worldclass technical support and service help provide customers with a lower total cost of ownership.
Western Digital is dedicated to providing a complete portfolio of hard drives to create environments for data to thrive.
High Workload Rating
Delivering dependable performance to any storage environment, Ultrastar hard drives are designed with a workload rating up to 550TB per year , among the highest of any 3.5-inch hard drive.
HelioSeal® Technology
Featured in over 20 million shipped Western Digital hard drives2, HelioSeal technology enables the highest capacities and less turbulence on large storage arrays. And now on its fifthgeneration design, HelioSeal technology is field-tested and proven to deliver high capacity, reliability, and power efficiency you can trust.
Enterprise-class Storage to Rely On
With up to 2.5 million hours MTBF rating, 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.
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 drives 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.
