They have a workload rating up to ten times higher than desktop hard drives. With the latest technologies, they offer reliability, energy efficiency, and enterprise-class performance. Designed from the ground up as extremely robust data storage solutions, Ultrastar hard drives are the perfect choice for your business.

High workload rating: Ultrastar hard drives provide reliable performance in any storage environment, offering up to 550 TB per year, which is ten times the workload rating of desktop hard drives. Thanks to the latest technologies, Ultrastar hard drives are characterized by reliability, energy efficiency, and enterprise-class performance.

Enterprise-class storage you can rely on: With an MTBF of up to 2.5 million hours, Ultrastar hard drives deliver immense reliability and durability for continuous operation in demanding storage environments.

HelioSeal technology: Western Digital has shipped over 30 million hard drives with HelioSeal technology (models starting from 10 TB), enabling greater capacity and higher reliability in large storage arrays. The now available 5th generation of HelioSeal technology demonstrably offers high reliability, energy efficiency, and storage capacity.

Vibration protection: The improved RVS technology (Rotational Vibration Safeguard) consists of sophisticated electronics for hard drive monitoring and real-time correction of linear and rotational vibrations, achieving better performance in high-vibration environments than conventional desktop hard drives.

Two-stage actuator technology: Ultrastar hard drives achieve the highest precision thanks to their head positioning system with two-stage actuators. A primary drive ensures coarse positioning, while fine adjustment is made by a highly precise piezoelectric drive.
