More Value to the Data Center with Maximum Capacity, Power Efficiency and Reliability

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 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 HDDprovides the highest reliability rating available of all HDDs on the market today by building on the successful design of it’s 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

Data Durability and Data Security to Support Compliance and Privacy Requirements
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 error conditions. The Ultrastar He12 HDD is a best-fit for object storage implementations with its massive capacity and industry-leading reliability rating. Compliance and privacy requirements drive the need for increased data security. The Ultrastar He12 HDD offers security and encryption options to help protect data from unauthorized use, including TCG options on both SATA and SAS models.
