The Dell 0PRF0M / Western Digital Ultrastar DC HC520 (HUH721212AL4200) is a high-performance enterprise-grade 12TB SAS hard drive engineered for demanding data centre and storage array environments. Built on Western Digital’s proven Ultrastar platform, this 3.5" drive delivers exceptional reliability, endurance, and consistent throughput, making it ideal for mission-critical workloads. With a 12Gb/s SAS interface and 7,200 RPM spindle speed, it is designed to handle continuous 24/7 operation in enterprise RAID and SAN configurations.
At the core of its performance is a 256MB cache buffer, enabling efficient data handling, reduced latency, and improved sustained transfer rates under heavy multi-user workloads. The drive utilises helium-filled technology, which reduces internal friction and power consumption while allowing higher storage density and improved thermal efficiency compared to traditional air-filled drives. It also supports 4Kn native sector formatting, ensuring compatibility with modern enterprise storage systems optimised for large-capacity, high-efficiency data processing.
This drive is widely deployed across Dell enterprise storage platforms, including PowerEdge servers and Dell Storage / Compellent arrays, where reliability and data integrity are critical. Designed for RAID environments and large-scale storage infrastructure, the Ultrastar DC HC520 offers a strong balance of capacity, endurance, and enterprise-class performance. It is an ideal solution for data archiving, virtualisation, cloud storage backends, and high-availability server deployments requiring consistent 24/7 operation.
