12.0TB Ultrastar® He12 Enterprise Class Hard Disk Drive

3.5-Inch | SATA 6.0Gb/s | 7200RPM | 256MB Cache
High Capacity. Low Power
More Value to the Data Center with Maximum Capacity, Power Efficiency and Reliability
Laying the foundation for a worry-free data center, Western Digital delivers capacity to conquer the data explosion – Ultrastar® He12 HDD. Designed to handle workloads up to 550TB per year, the Ultrastar He12 HDD is the industry's first 12TB drive and uses PMR technology to make it drop-in ready for any enterprise-capacity application or environment. The stable internal environment created by fourth-generation HelioSeal®technology enables a new 8-disk design, increasing the capacity by 20% when compared to the 7-disk design of the prior generation.
This highest capacity helium drive offers the lowest power profile in the industry to help data center architects meet eco-environmental goals and requirements. Targeted at 2.5M hours MTBF, the Ultrastar He12 HDD provides the highest reliability rating available of all HDDs on the market today by building on the successful design of its 10TB, 8TB and 6TB predecessors. Trust HGST and the Ultrastar He12 HDD 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 He12 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 efficiency (Watts/ TB), and is 25% more reliable, rated at 2.5M hours MTBF.
Data-center ready features like a second-generation dual-stage actuator the HGST Micro-Actuator enhance head-positioning accuracy to deliver better performance, data integrity and overall drive reliability, especially in multi-drive environments where operational vibration is present.
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 He12 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 He12 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 He12 extends the Western Digital 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, Western Digital products help the world harness the power of data.
