Description
WD Ultrastar DC HC520 12 TB Hard Drive – Internal – SAS (12Gb/s SAS) – 7200rpm – 5 Year Warranty – 20 Pack 26.1MM 12GB 256MB 7200RPM SAS ULTRA
Driving up Capacity and Driving Down TCO
The Ultrastar DC HC500-series is designed for public and private cloud environments where storage density and cost-efficient infrastructure is critical.
More Value to the Data Center with Capacity
Power Efficiency and Reliability
Laying the foundation for a worry-free data center
Western Digital delivers capacity to conquer the data explosion – Ultrastar® DC HC520
previously known as Ultrastar He12 and part of our HC500 series of helium-filled hard drives. Designed to handle workloads up to 550TB per year
the Ultrastar DC HC520 is the industry’s first 12TB1 drive and uses traditional perpendicular magnetic recording (PMR) technology to make it dropin 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
Ultrastar DC HC510. This high capacity helium drive 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 MTBF2
the Ultrastar DC HC520 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 Western Digital and the 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 8TB Ultrastar air-filled drives
this HelioSeal hard drive provides 50% more capacity
uses 52% less power (Watts/TB)
and is 25% more reliable
rated at 2.5M hours MTBF. Datacenter ready features like a second generation dual-stage actuator-the Western Digital 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. 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.
