Industry’s Best Capacity, Power Efficiency and Reliability Delivers Value to the Data Center

Laying the foundation for a worry-free data center, Western Digital delivers an exceptional capacity hard drive for the enterprise – Ultrastar DC HC520, previously known as Ultrastar He10 and part of our HC500 series of helium-filled hard drives. Designed to handle workloads up to 550TB per year, the Ultrastar DC HC520 uses PMR technology and is the industry’s first 10TB drive that is drop-in ready for any enterprisecapacity application or environment. Based on field proven, third-generation HelioSeal® technology, it offers one of the lowest power profiles in the industry to help data center architects meet eco-environmental goals and requirements. Targeted at 2.5M hours MTBF, the DC HC520 provides the highest reliability rating available of all HDDs on the market today by building on the successful design of its 8TB and 6TB predecessors. Trust Western Digital and Ultrastar DC HC520 to deliver more capacity, more efficiency, more reliability and more value to your data center.

HelioSeal® Technology Helps Solve Challenges Facing Next Generation Data Centers

Data centers are facing growing pressures. Data volume is expanding, operating costs are rising, yet budgets remain flat. Lowering the total cost of ownership (TCO) has become the focus of data center architects and the Ultrastar DC HC520 provides the best value proposition and greatest storage efficiency available. Compared to our 8TB air-filled drives, this HelioSeal hard drive provides 25% more capacity, uses 28% less idle power, is 43% more power efficient (Watts/TB), and is 25% more reliable, rated at 2.5M hours MTBF. New features include a second-generation, dual-stage actuator— the Western Digital Micro-Actuator—enhancing head-positioning accuracy to deliver better performance, data integrity and overall drive reliability, especially in multi-drive environments where operational vibration is present. Refer to our technical brief to learn more. A choice of 6Gb/s SATA and 12Gb/s SAS interface enables easy integration into high performance data centers.

Data Durability and Security with Industry-Leading Quality and Reliability

As drive capacity grows beyond single-digit TBs, object storage systems with erasure coding provide better data durability compared to RAID systems, given its tolerance for simultaneous errors conditions. Ultrastar DC HC520 is a best-fit for object storage implementations given its massive capacity and industry-leading reliability rating. Compliance and privacy requirements drive the need for increased data security. Ultrastar DC HC520 offers security and encryption options to protect data from unauthorized use, including a new option for TCG support on some SATA models.
