Key features

Handle Data Centre Workloads with Proven Technology

The combination of field-proven hardware with the latest innovative technologies delivers the performance, capacity and reliability needed to handle high-intensity workloads in 24x7 multi-user data centre environments.

Grow Capacity while Lowering Costs

Western Digital's energy-assisted perpendicular magnetic recording (ePMR) technology enables customers to grow capacities while lowering TCO (total cost of ownership) including both $/TB and OpEx.

Rapid Qualification and Integration

Combining hardware designs from generations of highly successful products with Conventional Magnetic Recording (CMR) technology ensures easy qualification, seamless integration and rapid adoption by existing customers.

Reliability You Can Trust

Built off the same platform that is deployed in thousands of data centres around the world, these drives deliver superior dependability and field-proven reliability for hassle free data storage.

Increase Density with Low Power

Western Digital's Triple-Stage Micro Actuator increases tracks-per-inch (TPI) while providing greater control over the actuator arm, enabling the highest capacities with low power.

Protected Against Vibration & Shock

Combined with Dynamic Fly Height technology, Western Digital offers exceptional drive reliability and protection from unexpected shock events.
