Economical Capacities and Fast Data Access for the Data Center

The Ultrastar DC HA340 HDD in 4TB, 6TB, and 8TB delivers efficiency and performance for traditional and legacy systems based on proven CMR technology. Designed for a variety of applications including traditional storage arrays, rack-mounted storage enclosures and server-based storage systems, these drives are offered at 7,200 RPM with 6Gb/s SATA and Advanced Format 512e format.

Technology innovation delivers efficiency and performance for legacy systems

Address data center requirements by providing legacy capacities from 4TB to 8TB while implementing the latest in HDD storage technologies.

Proven and cost-efficient design

Ultrastar DC HA340 drives are based on an air-based HDD platform with Conventional Magnetic Recording (CMR) technology in a 3.5-inch form factor. 

Performance and protection 

These 4TB, 6TB, and 8TB HDD's leverage a dual-stage microactuator to enhance head positioning accuracy for better drive performance. 

Designed for data center workloads

The Ultrastar DC HA340 is performance-optimized to handle heavy application workloads of up to 550TB²per year.

Built with reliability in mind 

This robust drive delivers dependability in intense data center environments with up to 2M hours MTBF³(projected). 

Quality and security

Provides additional peace of mind with a 5-year limited warranty. 

Engineered to handle high-intensity workloads with proven technology

Ultrastar Data Center HC555 hard drives are engineered to deliver the large capacity, strong performance and proven reliability needed to handle high-intensity workloads in 24?7 multi-user data center environments.

Handle Data Center 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 24?7 multi-user data center 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

Leveraging hardware designs from generations of highly successful products 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 centers 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 Actuator (TSA) increases tracks-per-inch (TPI) while providing greater control over the actuator arm, enabling the highest capacities with low power.

Meet Eco Goals with Helium

The stable internal environment created by our HelioSeal® technology enables this high-capacity helium drive to deliver one of the lowest power profiles in the industry.

Protected Against Vibration & Shock

Disturbances caused by increased vibration are anticipated and proactively counteracted by Rotation Vibration (RV) sensors and subtle shock events are automatically detected by multi-axis shock sensors and compensated for with dynamic fly height technology to maintain performance and protect data.

Trusted Reliability, Quality and World-Class Support

As an industry-leading hard drive manufacturer, Western Digital stands behind their Ultrastar hard drives with the assurance of a projected 2.5M-hour MTBF rating, a 5-year limited warranty and world-class support services to help create environments for data to thrive.
