Ultrastar He12

  • 12TB
  • 3.5-inch Helium Platform
  • Enterprise Hard Drive
  • Highest Capacity – 12TB PMR HDD, drop-in ready for capacity workloads
  • Lowest Power – 54% lower idle watts/TB than 8TB air-filled drives
  • Most 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 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.

MODEL NUMBERS: For a complete list of available model numbers, visit the P/N Selector tab.
CAPACITY: One MB is equal to one million bytes, one GB is equal to one billion bytes and one TB equals 1,000GB (one trillion bytes) when referring to hard drive capacity. Accessible capacity will vary from the stated capacity due to formatting and partitioning of the hard drive, the computer’s operating system, and other factors.
RELIABILITY: MTBF/AFR - Specifications are based on a sample population and are estimated by statistical measurements and acceleration algorithms under typical operating conditions for this drive model. MTBF and AFR ratings do not predict an individual drive’s reliability and do not constitute a warranty.
SECTOR SIZE: Advanced Format drive means 4K (4096-byte) physical sectors.
DATA BUFFER: Portion of buffer capacity used for drive firmware.
TRANSFER RATE: MiB/s is 220 bytes, MB/s is 106 bytes.
SEEK TIME: Excludes command overhead.
OPERATING POWER: SATA models: 8KB Queue Depth = 1 @ 40 IOPS, SAS models: 4KB Queue Depth = 4
IDLE POWER: specification is based on use of Idle_A
