- High Capacity 12TB PMR HDD, drop-in ready for capacity
workloads
- Low Power 52% lower idle W/TB than 8TB Ultrastar
air-filled drives
- More Reliable Highest MTBF rating for an HDD at 2.5M
hours
Laying the foundation for a worry-free data center, HGST 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 industrys 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 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 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.
