High Workload Rating
Delivering dependable performance to any storage environment, Ultrastar hard drives are designed with a workload rating up to 550TB per year 1, among the highest of any 3.5-inch hard drive.
Featured in over 20 million shipped Western Digital hard drives 2, HelioSeal technology enables the highest capacities and less turbulence on large storage arrays. And now on its fifth – generation 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.
All 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.
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.
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.
7200 RPM Class
This 7200 RPM-class hard drive delivers the fastest performance with the highest workload rating of any high-capacity drive from Western Digital. Ensure you have the most capable hard drive regardless of the application with Ultrastar hard drives.
