Wd Ultrastar Dc Hc520 12Tb 7200 Rpm Sata 6Gb/S 256Mb Cache 3.5-Inch Enterprise Hard Drive (Huh721212Ale604)

Laying the foundation for a worry-free data center, Western Digital delivers 12TB capacity drive to conquer the data explosion – Ultrastar® DC HC520, previously known as Ultrastar He12 and part of our HC500 series of helium-filled hard drives. Designed to handle workloads up to 550TB per year, the Ultrastar DC HC520 is the industry’s first 12TB 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, Ultrastar DC HC510. This high capacity helium drive offers one of the lowest power profiles in the industry to help data center architects meet eco-environmental goals and requirements. Targeted at 2.5M hours MTBF, the Ultrastar 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 Ultrastar DC HC520 to deliver more capacity, more efficiency, more reliability and more value to your data center.
