The Western Digital Ultrastar DC HC550 16TB SAS-3 internal hard drive is engineered to meet the rigorous demands of modern enterprise data centers. By providing a massive 16TB of storage in a standard 3.5-inch form factor, this drive helps organizations optimize their data center architecture, reducing the need for additional racks and lowering overall Total Cost of Ownership (TCO).

Built on a sophisticated 9-disk platform, the DC HC550 incorporates cutting-edge innovations such as Energy-Assisted Magnetic Recording (EAMR) and a Triple Stage Actuator to maximize areal density and performance. The inclusion of 6th generation HelioSeal technology replaces internal air with helium, significantly reducing power requirements and friction while maintaining cooler operating temperatures for long-term reliability.

Designed for high-scale environments, this drive is ideal for cloud storage, big data analytics, and distributed file systems. With a 2.5 million hour MTBF rating and an annual workload capacity of 550TB, it offers the durability required for object storage implementations. The drive also supports advanced security features, including self-encrypting drive options to protect sensitive information from unauthorized access.
