Western Digital 12TB HDD Ultrastar DC SATA 6 Gb/s 7200 RPM 3.5-Inch, HT0F30146, Silver

Designed: with a workload rating up to 550TB per year, 10X desktop rating (Workload rate is defined as the amount of data transferred to or from the hard drive; Workload Rate is annualized (TB transferred X (8760/ recorded power on hours); Workload Rate will vary depending on your hardware and software components and configurations Up to 2. 5M hours MTBF: Five generations of HelioSeal technology: Rotational: Vibration Safeguard (RVS) technology for vibration protection Driving up Capacity and Driving Down TCO The Ultra star DC HC500-series is designed for public and private cloud environments where storage density and cost-efficient infrastructure is critical. More Value to the Data Centre with Capacity, Power Efficiency and Reliability Laying the foundation for a worry-free data centre, Western Digital delivers capacity to conquer the data explosion - Ultra star DC HC520, previously known as Ultra star He12 and part of our HC500 series of helium-filled hard drives. Designed to handle workloads up to 550TB per year, the Ultra star DC HC520 is the industry's first 12TB1 drive and uses traditional perpendicular magnetic recording (PMR) technology to make it dropin ready for any enterprise-capacity application or environment. The stable internal environment created by fourth-generation HelioSeal technology enables a new 8-disk design, increasing the capacity by 20% when compared to the 7-disk design of the prior generation, Ultra star DC HC510. This high capacity helium drive offers one of the lowest power profiles in the industry to help data centre architects meet eco-environmental goals and requirements. Targeted at 2. 5M hours MTBF2, the Ultra star DC HC520 provides the highest reliability rating available of all HDDs on the market today by building on the successful design of its 10TB, 8TB and 6TB predecessors. Trust Western Digital and the Ultra star DC HC520 to deliver more capacity, more efficiency, more reliability and more value to your data centre. HelioSeal Technology Helps Solve Challenges Facing Next Generation Data Centres Data centres are facing growing pressures. Data volume is expanding, operating costs are rising, yet budgets remain flat. Lowering the total cost of ownership (TCO) has become the focus of data centre architects and the Ultra star DC HC520 provides the best value proposition and greatest storage efficiency available. Compared to 8TB Ultra star air-filled drives, this HelioSeal hard drive provides 50% more capacity, uses 52% less power (Watts/TB), and is 25% more reliable, rated at 2. 5M hours MTBF. Datacentre ready features like a second generation dual-stage actuator-the Western Digital Micro Actuator-enhance head-positioning accuracy to deliver better performance, data integrity and overall drive reliability, especially in multi-drive environments where operational vibration is present.
