Available today. That’s the power of helium. Delivering the industry’s leading capacity at 8TB, Ultrastar He8 is based on the widely accepted and proven HelioSeal® platform. HelioSeal technology replaces air with helium inside the drive, reducing air turbulence and enabling 7Stac™, a seven-disk design in a traditional 3.5-inch form factor. Ultrastar He8 goes beyond what any air-based HDD can do and seamlessly integrates into virtually any mainstream enterprise environment. Cooler and quieter with industry-leading power efficiency (Watts/TB) and no-compromise performance, the Ultrastar He8 lays the foundation for future growth in massive scale-out environments. TCOptimized™ – Increasing Storage Efficiency to Drive Down Data Center TCO We recognize the growing pressures that data centers face. Volume is expanding, operating costs are rising while budgets remain flat. Lowering the total cost of ownership (TCO) has become the focus of data center architects. Ultrastar He8 provides the best TCO value proposition and delivers greater storage efficiency with breakthroughs in capacity, power efficiency and best-in-class performance. This HelioSeal hard drive achieves up to 3X higher random write performance than the prior generation, Ultrastar He6, thanks to HGST media cache architecture, a disk-based caching technology. He8 offers a 12Gb/s SAS (6Gb/s SATA) interface for easy integration into high performance data centers. Features like Rebuild Assist dramatically reduce RAID rebuild times and maintain system performance during the rebuild process. Learn more in our Rebuild Assist technical brief. Data Security with Industry-Leading Quality and Reliability Compliance and privacy requirements drive the need for increased data security. Ultrastar He8 offers security and encryption options to protect data from unauthorized use. Instant Secure Erase (ISE) models expedite drive redeployment and retirement. Encryption models protect data with hardware-based encryption, including a Trusted Computing Group (TCG) option with FIPS 140-2 certification, Level 2. The Ultrastar He8 extends HGST’s long-standing tradition of reliability leadership with a 2.5M-hour MTBF rating and a 5-year limited warranty. HGSTs drive reliability and security options also help lower data center TCO.

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. 2 MTBF and AFR targets are based on a sample population and are estimated by statistical measurements and acceleration algorithms under median operating conditions. MTBF and AFR ratings do not predict an individual drive’s reliability and do not constitute a warranty. 3 Advanced Format drive: 4K (4096-byte) physical sectors 4 Portion of buffer capacity used for drive firmware 5 MiB/s is 220 bytes, MB/s is 106 bytes 6 Excludes command overhead 7 SATA models: 8K Queue Depth = 1, SAS models: 4K Queue Depth = 4 8 Idle specification is based on use of Idle_A 1 Specifications SATA Models Model No. SAS Models SATA Models HUH7280xxALN60y HUH7280xxALE60y HUH7280xxAL420y HUH7280xxAL520y Acoustics Interface SATA 6Gb/s SAS 12Gb/s Power Capacity1 (TB) 8TB / 6TB ← Configuration Format: Sector size3 (bytes) Max.
