WD Ultrastar He8 HUH728080AL4200 - Hard drive - 8 TB - internal - 3.5" - SAS 12Gb/s - 7200 rpm - buffer: 128 MB

Key Features and Benefits:

• HelioSeal delivers twice the capacity using one-quarter less power
  One-third more capacity and 23% lower energy consumption. 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
  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. 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.
• 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 2M-hour MTBF rating. HGSTs drive reliability and security options also help lower data center TCO.
