HGST Ultrastar DC HC520 HUH721212ALE604 12 TB Hard Drive - 3.5" Internal - SATA (SATA/600) - 7200rpm - 550 TB TBW
Ultrastar® hard drives feature up to 10 times the workload rating of desktop drives and employ advanced technologies
for enterprise-class reliability, power efficiency and performance. Designed from the ground up to be an ultra-robust storage device
Ultrastar drives are the perfect solution for your business.
High Workload Rating
Delivering dependable performance to any storage environment, Ultrastar hard drives are designed with a workload rating up to 550TB per year, among the highest of any 3.5-inch hard drive.
Enterprise-class Storage to Rely On
Ultrastar is our top-end drive for data centers. With up to 2.5 million hours MTBF, Ultrastar hard drives deliver reliability and
durability, are built for yearly operation (24x7x365) within the most demanding storage environments, and are backed with a 5-year limited warranty.
HelioSeal™ Technology
Featured in over 30 million Western Digital hard drives shipped, HelioSeal technology allows for higher capacities and lower power
on large storage arrays. And now on its 5th generation design, HelioSeal technology is field-tested and proven to deliver high
capacity, reliability, and power efficiency you can trust. HelioSeal is a key technology on 10TB capacities and above.
Vibration Protection
Enhanced Rotational Vibration Safeguard (RVS) technology uses sophisticated electronics to monitor the drive and correct linear
and rotational vibrations in real time for improved performance versus traditional desktop drives in high-vibration environments.
Dynamic Fly-height Technology
Each read-write head's fly height is adjusted in real time to ensure consistent performance for reduced errors and optimized
reliability.
Dual-stage Actuator Technology
Ultrastar drives feature a dual-stage actuator head positioning system for a high degree of accuracy. The primary stage provides
course displacement while the secondary stage uses piezoelectric motion to fine tune the head positioning to a higher degree of
precision.
Compatibility testing
All Ultrastar hard drives are extensively tested across a variety of popular OEM storage systems, SATA controllers, and host bus
adapters to ensure ease of integration for a plug and play solution.

ULTRASTAR ® DC HC520 - 12TB
The Ultrastar DC HC500 series SAS or SATA HDD are-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 12TB capacity drive 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 12TB 1 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 MTBF 2 , 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.
