Western Digital 0F14690 Ultrastar 7K4000 2TB HDD Internal

The Western Digital (HGST) Ultrastar 7K4000 HUS724020ALA640 is a 2TB enterprise-class hard drive built for environments where reliability is non-negotiable. Spinning at 7200 RPM with a SATA 6Gb/s interface, it delivers consistent throughput for sequential workloads such as file serving, backup targets, and bulk data storage. The Ultrastar line has long been regarded as one of the most reliable mechanical drive families available, and the 7K4000 continues that legacy with engineering focused on low vibration, thermal management, and sustained operation.

This drive is well suited for rack-mounted servers, NAS appliances, and other multi-drive configurations where drives run around the clock. Its advanced power management features help reduce overall energy consumption when deployed in arrays with many spindles. While the 2TB capacity may require more drives to meet large storage targets compared to higher-capacity models, the trade-off is a proven track record of durability that many administrators prefer when building out reliable storage pools.
