WD Ultrastar 7K3000 HUS723020ALS640 - Hard drive - 2 TB - internal - 3.5in - SAS 6Gb/s - 7200 rpm - buffer: 64 MB

Combining 7200 rpm performance and granular power control. Operating at 7200 rpm, the Hitachi Ultrastar 7K3000 offers better overall performance than slower RPM capacity-oriented drives, and does so at impressively low power consumption rates. The Ultrastar 7K3000 can help data centers achieve lower AC power and HVAC requirements. With five advanced power management modes, the Ultrastar 7K3000 achieves a 59% reduction in watts during low RPM idle mode, and uses less than 1 W during standby/sleep modes, freeing up precious headroom for growing enterprise needs. Delivering industry-leading quality and reliability. The Hitachi Ultrastar 7K3000 is a 7200 rpm hard drive rated at 2.0 million hours MTBF. The Ultrastar 7K3000 represents the fifth-generation Hitachi 5-platter mechanical design. When the high quality and reliability are a top requirement, customer field data proves that the Ultrastar 7K3000 delivers by reducing downtime, eliminating service calls and keeping TCO to a minimum. Engineered for high reliability, the Ultrastar 7K3000 is not only put through grueling design tests during development but must also pass stringent ongoing reliability testing during manufacturing. Increasing capacity density by 50%. Recent measures such as data de-duplication and thin provisioning have not been able to stem the explosive petabyte (PB) growth requirements in cloud storage and data centers. Pervasive Internet computing with remotely stored email, pictures and social media, all being accessed from light-weight tablet and notebook computers, is changing consumer expectations. Ongoing worldwide government data retention regulations and security requirements are also driving up data center and private cloud storage needs. At the same time, tile space and megawatts remain at a premium, while in some highly built-out metropolitan areas both are at an absolute "no-growth" state. To meet these demands, the Ultrastar 7K3000 delivers 50% more capacity in the same footprint. It is now possible to achieve a colossal 1.8 PB in the footprint of a standard 19-inch enterprise storage rack by stacking ten 4 U, 60-bay enclosures.
