Western Digital Ultrastar DC HC520 12TB SATA Enterprise Hard Drive

Product Features

12TB Enterprise Storage: The Western Digital Ultrastar DC HC520 provides 12TB of high-capacity storage for enterprise applications, data centers, servers and large-scale storage infrastructures.

Designed for Data Centers: The Ultrastar DC HC500 series is engineered for public and private cloud environments where storage density, reliability and infrastructure efficiency are critical requirements.

7200 RPM Enterprise Performance: A 7200 RPM spindle speed delivers consistent performance for demanding enterprise storage workloads, including large data repositories, cloud infrastructure and server applications.

SATA 6Gb/s Interface: The SATA interface allows the drive to integrate with compatible enterprise servers, storage arrays, NAS systems and data center infrastructure.

Up to 255MB/s Transfer Rate: With transfer performance of up to approximately 255MB/s, the Ultrastar DC HC520 is designed to efficiently handle large-scale enterprise data transfers.

HelioSeal® Technology: Western Digital’s HelioSeal technology creates a stable helium-filled internal environment that enables higher storage density while helping reduce power consumption and improve operating efficiency.

8-Disk Internal Design: The helium-filled architecture enables an eight-disk design, allowing Western Digital to provide 12TB of capacity within a standard 3.5-inch enterprise hard drive form factor.

Up to 550TB/Year Workload: The Ultrastar DC HC520 is designed to handle enterprise workloads of up to 550TB per year, making it suitable for considerably more demanding environments than conventional desktop hard drives.

2.5 Million Hours MTBF: A targeted MTBF rating of 2.5 million hours reflects the drive’s enterprise-focused reliability for large-scale and always-on storage environments.

Power-Efficient Enterprise Storage: Helium technology helps reduce power consumption per terabyte, supporting lower operating costs and improved storage efficiency in large data center deployments.

Dual-Stage Actuator Technology: Western Digital’s Micro Actuator technology enhances head-positioning accuracy, helping improve performance, data integrity and reliability in demanding multi-drive environments.

Designed for Multi-Drive Environments: The drive is engineered to maintain dependable operation in enterprise systems where multiple drives operate together and rotational vibration can affect storage performance.

High Storage Density: With 12TB available from a single 3.5-inch drive, organizations can increase overall storage density while reducing the physical infrastructure required for large data volumes.
