WD Ultrastar DC HC520 12TB 3.5 HDD SATA 512E ISE 7200RPM Helium 0F29590/HUH721212ALE600

The Western Digital Ultrastar DC HC520 is a 12TB, 3.5" hard drive with a speed of 7200 RPM, part of the Ultrastar DC HC500 Series. It is designed to provide high capacity for massive data needs and significantly reduce the total cost of ownership for cloud and hyperscale data centers.

As data requirements grow, there is an increasing need for higher capacity solutions across various applications and workloads. The Ultrastar DC HC500 series helps address these demands, making it easier to manage the data boom. Leveraging HelioSeal technology, the sole fifth-generation helium platform in the industry, the DC HC500 series is crafted with cloud environments in mind—both public and private. It focuses on storage density, cost per terabyte, and power efficiency to offer the most economically viable infrastructure. This advanced technology facilitates higher capacities, enhanced reliability, and exceptional power efficiency, ultimately lowering the total cost of ownership for both cloud and enterprise users.

Western Digital's HelioSeal technology is a groundbreaking development that meets the complicated requirements of modern data centers. This method hermetically seals the hard drive and substitutes the air inside with helium, which is substantially less dense than air. This less dense environment redefines the limitations of traditional high-capacity hard drives, resulting in significant improvements in efficiency, reliability, and overall value.

The Ultrastar DC HC520 offers a higher capacity with a 12TB CMR HDD, making it immediately usable for capacity-focused workloads. It also consumes 52% less power at idle per terabyte than 8TB Ultrastar models filled with air. Moreover, it boasts an outstanding Mean Time Between Failures (MTBF) rating of 2.5 million hours, offering unmatched reliability for a hard disk drive.
