One-third more capacity and 23% lower energy consumption. Available today. That’s the power of helium. Delivering high 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 excellent power efficiency (Watts/TB) and no-compromise performance, the Ultrastar He8 lays the foundation for future growth in massive scale-out environments. 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. Designed to handle workloads of up to 550TB per year, He8 offers a 12Gb/s SAS (6Gb/s SATA) interface for easy integration into high performance data centers.
