product_title: HGST - WD Ultrastar DC HC520 HDD | HUH721212ALE600 | 12TB 7.2K SATA 6Gb/s 256MB Cache 3.5-Inch Helium Data Center Internal Hard Disk Drive
product_description: <b>More Value to the Data Center with Maximum Capacity, Power Efficiency and Reliability</b> <br><br> Laying the foundation for a worry-free data center, Western Digital delivers capacity 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. 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. <br><br> <b>HelioSeal Technology Helps Solve Challenges Facing Next Generation Data Centers</b> <br><br> Lowering the total cost of ownership (TCO) has become the focus of data center architects and the Ultrastar DC HC520 provides the best value proposition and greatest storage efficiency available. Compared to 8TB Ultrastar 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.
product_bullet_point: Instant secure erase (ISE), endurance optimized with field-proven helium design
  Dual safe firmware for reliable updates, 2.5M MTBF, power efficient with low idle W/TB than air-filled drives
  High capacity storage for big data storage applications, perfect for cloud and hyperscale storage that need durability and security
  Optimal for high-density data centers and centralized video surveillance for reliability, capacity density, and power efficiency
  12TB of storage capacity, SATA III interface, 256MB buffer, 7200 RPM spindle rotational speed
