ultrastar ? he 8 helioseal ? delivers twice the capacity using one-quarter less power one-third more capacity and 23% lower energy consumption. available today. thats the power of helium. delivering the industrys leading capacity at 8tb, ultrastar he 8 is based on the widely accepted and proven helioseal? plat - form. helioseal technology replaces air with helium inside the drive, reduc - ing air turbulence and enabling 7stac?, a seven-disk design in a traditional 3.5-inch form factor. ultrastar he 8 goes beyond what any air-based hdd can do and seamlessly integrates into virtually any mainstream enterprise environ - ment. cooler and quieter with industry-leading power eficiency (watts/tb) and no-compromise performance, the ultrastar he 8 lays the foundation for future growth in massive scale-out environments. tcoptimized ? C increasing storage eficiency to drive down data center tco we recognize the growing pressures that data centers face. volume is ex - panding, operating costs are rising while budgets remain flat. lowering the total cost of ownership (tco) has become the focus of data center architects. ultrastar he 8 provides the best tco value proposition and delivers greater storage eficiency with breakthroughs in capacity, power eficiency and best-in-class performance. this helioseal hard drive achieves up to 3x higher random write performance than the prior generation, ultrastar he 6 , thanks to hgst media cache architecture, a disk-based caching technology. he 8 ofers a 12gb/s sas (6gb/s sata) interface for easy integration into high perfor - mance 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 secu - rity. ultrastar he 8 ofers security and encryption options to protect data from unauthorized use. instant secure erase (ise) models expedite drive redeploy - ment 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 he 8 extends hgsts 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. hgst quality and service hgsts ultrastar he 8 extends the companys long-standing tradition of perfor - mance and capacity leadership. the proven drive design enables high reliabil - ity and availability to customer data. ultrastar quality, performance and world class technical support and service provides customers with a lower total cost of ownership over previous generations.hgst drives are backed by an array of technical support and services, which may include customer and integration assistance. hgst is dedicated to providing a complete portfolio of hdd, ssd and software solutions to help the world harness the power of data. highlights ? industrys leading 8tb capacity 1 in a standard 3.5-inch form factor ? industrys best idle and active power eficiency (watts/tb) ? reliable, field-proven, 2nd generation helioseal? process and 7stac? design ? compared to 6tb air drives C 33% more capacity C 23% lower idle power C 44% more power eficient (watts/tb) ? sata 6gb/s and sas 12gb/s C 12gb/s sas compatible with next gen data centers; backwards compatible with 6gb/s sas ? 2.5m hours mtbf 2 rating & 5-year limited warranty ? instant secure erase (ise) & self-encrypting drive (sed) options ? advanced format 4kn and 512e models applications environments ? enterprise and data center applications where capacity density and power eficiency are paramount ? cloud & hyperscale storage ? massive scale-out high-density data centers (mso) ? distributed files systems like ceph? and hadoop? to support big data analytics ? raid arrays ? video surveillance & content distribution ? ideal for all mainstream enterprise capacity applications 23% lower idle power* 44% better watts/tb* 33% more capacity* 8tb and 6tb | 7200 rpm sata 6gb/s and sas 12gb/s * vs. 6tb air drives 3.5-inch helium platform enterprise hard disk drives data sheet
