HGST WD Ultrastar DC HC520 12TB HDD

Delivering More Value to Data Centers with Maximum Capacity, Power Efficiency, and Reliability

Laying a solid foundation for a worry-free data center, Western Digital introduces the Ultrastar DC HC520 – previously known as the Ultrastar He12 – a part of the HC500 series of helium-filled hard drives. Designed to tackle data explosion, this 12TB drive, the industry's first, utilizes traditional perpendicular magnetic recording (PMR) technology, making it a seamless fit for any enterprise-capacity application or environment.

Built to handle workloads up to 550TB per year, the Ultrastar DC HC520 offers one of the lowest power profiles in the industry, empowering data center architects to meet their eco-environmental goals and requirements. Targeting a remarkable 2.5M hours MTBF, this high-reliability hard drive surpasses the market's highest reliability rating, building upon the successful design of its 10TB, 8TB, and 6TB predecessors.

Trusted by Western Digital, the Ultrastar DC HC520 delivers more capacity, efficiency, reliability, and value to data centers, helping tackle the challenges faced by next-generation facilities.

Lowering Total Cost of Ownership (TCO) has become the primary focus for data center architects, and the Ultrastar DC HC520 provides the best value proposition and greatest storage efficiency available. Compared to 8TB Ultrastar air-filled drives, this hard drive offers 50% more capacity, uses 52% less power (Watts/TB), and is 25% more reliable, rated at 2.5M hours MTBF.

The "Power Disable" feature, a new industry standard for SATA devices, allows the host system to perform a hard reset on the hard drive (HDD), while the Instant Secure Erase (ISE) functionality is endurance-optimized with field-proven helium design. Additionally, the dual-safe firmware ensures reliable updates, further enhancing the drive's 2.5M MTBF and power-efficient performance compared to air-filled drives.

Ideal for big data storage applications, cloud, and hyperscale storage that demand durability and security, the Ultrastar DC HC520 is optimized for high-density data centers and centralized video surveillance, delivering reliability, capacity density, and power efficiency.

Boasting 12TB of storage capacity, a SATA III interface, a 256MB buffer, and a 7200 RPM spindle rotational speed, the Ultrastar DC HC520 offers up to 2.5M hours MTBF, accompanied by a 5-year limited OEM warranty direct from the Authorized Reseller.
