Ultrastar He10

Massive Capacity, Power Efficiency and Reliability Delivers Value to the Data Center
Laying the foundation for a worry-free data center, HGST delivers an exceptional capacity hard drive for the enterprise – Ultrastar He10. Designed to handle workloads up to 550TB per year, the Ultrastar He10 uses PMR technology and is the industry’s first 10TB drive that is drop-in ready for any enterprise-capacity 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 He10 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 HGST and Ultrastar He10 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 He10 addresses this challenge by delivering both value and efficiency. Compared to 8TB air-filled drives, this HelioSeal hard drive provides 25% more capacity, uses 34% less idle power, is 44% 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 HGST 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 HMA 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 He10 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 He10 offers security and encryption options to protect data from unauthorized use, including a new option for TCG support on some SATA models.

HGST Quality and Service
Ultrastar He10 extends the HGST brand’s long-standing tradition of performance and capacity leadership. The proven drive design enables high reliability and availability to customer data. Ultrastar quality, performance and world class technical service and support provides customers with a lower total cost of ownership over previous generations. HGST drives are backed by an array of technical support and services, which may include customer and integration assistance. Dedicated to providing a complete portfolio of devices and systems, HGST products help the world harness the power of data.
