Description
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 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. 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. -
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. Compliance and privacy requirements drive the need for increased data security. The Ultrastar DC HC520 offers security and encryption options to help protect data from unauthorized use, including TCG SAS models.
