Western Digital Ultrastar (HGST) HC550 18TB Enterprise Hard Drive WUH721818ALE6L4 Overview : High Capacity for Massive Data and Lower Total Cost of Ownership Extreme Capacity 18TB CMR HDD for hyperscale, cloud, and enterprise storage Areal Density 9-disk platform with 6th generation HelioSeal technology and energy assisted recording drives capacity/density leadership TCO Cost-optimized configurations for every important capacity point Driving Up Capacity and Driving Down TCO for Cloud and Hyperscale Data Centers The breadth and depth of Big Data is driving the universal need for higher capacities across a broad spectrum of applications and workloads. Laying the foundation for a worry-free data center, Western Digital delivers the capacity to conquer the data explosion with the Ultrastar DC HC500 series of hard drives. Built using HelioSeal technology, the industry’s only fifth-generation helium platform, the DC HC500 series is designed for public and private cloud environments, where storage density, Watts/TB and $/TB are critical for creating the most cost-efficient infrastructure. HelioSeal technology is key to achieving higher drive capacities, greater reliability ratings and extreme power efficiency. The result is a lower Total Cost of Ownership (TCO) for our cloud and enterprise customers. Solves TCO Challenges
