    Western Digital Ultrastar DC HC320 (8TB) 7200rpm SATA 6Gb/s Hard Drive


    Western Digital 8TB DC HC320 HDD. Bring mid-capacity drives to your data center

    The Ultrastar DC HC300-series provides low to mid-capacity drives that are economical to acquire, yet deliver quick and reliable data access for traditional data center applications.

    Economics and Access Speed: Key Requirements for Low Capacity SATA HDDs in the Data Center

    As the industry evolves to develop purpose-built solutions for growing data storage requirements, IT managers continue to rely on lower capacity drives that are economical to acquire, yet deliver quick and reliable data access for traditional data center applications

    Designed to handle workloads up to 550TB per year, Ultrastar® DC HC320 is an 8TB HDD that helps address economic and access requirements of many traditional IT workloads

    Low capacity drives also help address architecture limitations

    Part of our mid-capacity DC HC300 series, the Ultrastar DC HC320 is designed for traditional storage and server applications as well as distributed and scalable computing, including block and file storage architectures, providing fast 7,200 RPM performance and lower acquisition cost to help ease budget constraints.

    Ultrastar DC HC320 is offered with either 6Gb/s SATA or 12Gb/s SAS interface in a 512e format.

    Technology Innovation Delivers Efficiency and Performance for Traditional IT Systems

    Ultrastar DC HC320 is based on a proven 5-disk air platform design that uses conventional magnetic recording (CMR) technology in a 3.5-inch large form factor

    Compared to the prior generation, Ultrastar 7K6000, the DC HC320 delivers 33% more capacity, up to 12% performance boost and uses slightly larger-diameter media

    It features a second-generation, dual-stage micro actuator to enhance head positioning accuracy for better drive performance

    Write performance gains are also supported by Western Digital's media cache architecture, a disk-based caching technology that provides a large cache area on the disk, which also improves reliability and data integrity during unexpected power loss

    Finally, the addition of flash-based non-volatile cache (NVC) on both SATA and SAS models helps improve write performance

    The Ultrastar DC HC320 also includes a Rebuild Assist feature, which helps dramatically reduce RAID rebuild times and maintain system performance during the rebuild process


    Ultrastar® hard drives feature up to 10 times the workload rating of desktop drives and employ advanced technologies for enterprise-class reliability, power efficiency and performance. Designed from the ground up to be an ultra-robust storage device, Ultrastar drives are the perfect choice for your business.

    Best-fit Applications

    • Enterprise servers and storage systems
    • Business-critical applications needing reliable, robust high-capacity storage
    • Surveillance analytics and industrial applications

    Ultrastar Advantage

    The Ultrastar family delivers a long-standing tradition of reliability leadership with MTBF ratings of at least 2M hours and a 5-year limited warranty. Ultrastar quality, capacity, power efficiency, and world-class technical support and service help provide customers with a lower total cost of ownership.

    Western Digital is dedicated to providing a complete portfolio of hard drives to create environments for data to thrive.

    High Workload Rating

    Delivering dependable performance to any storage environment, Ultrastar hard drives are designed with a workload rating up to 550TB per year, among the highest of any 3.5-inch hard drive.

    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.

    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.
