Description
Ultrastar SATA Series hard drives are built from the ground up to be an ultra-robust storage device. Designed with a workload rating up to 550TB per year, Ultrastar drives are the perfect choice for business-critical applications like enterprise servers, storage subsystems, surveillance analytics and industrial environments. Higher capacities are made by HelioSeal technology, delivering the lowest $/TB and Watts/TB to minimize total cost of ownership (TCO). Lower capacity drives are built using traditional air-filled technology, ideal for users looking for lower acquisition cost
High Workload Rating
Delivering dependable performance to any storage environment, Ultrastar hard drives are designed with a workload rating up to 550TB per year1, 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 4th 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.
Compatibility Testing
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.
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.
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.
