WD Ultrastar 20TB DC HC555 | Enterprise Hard Drive | SATA 6Gb/s, 512MB Cache, RPM@7200, Up to 285MB/s Transfer Speed | MODEL NO-0B48724/WUH722020CLE6L4

WD Ultrastar 20TB DC HC555 is engineered for today’s most demanding data center environments, offering a powerful combination of high capacity, energy efficiency, and proven reliability. Designed to handle 24×7 multi-user workloads, this drive is ideal for cloud storage, hyperscale deployments, and enterprise data centers requiring maximum density and uptime.

Built on a trusted platform and leveraging energy-assisted perpendicular magnetic recording (ePMR), the HC555 enables data centers to scale capacity while reducing total cost of ownership (TCO). It features Triple-Stage Actuator (TSA) technology to increase track density and improve performance, along with HelioSeal® technology, which reduces turbulence and power consumption by operating in a helium-sealed environment.

Reliability is paramount, with rotation vibration (RV) sensors, multi-axis shock sensors, and dynamic fly height technology working together to protect data from mechanical disturbances. With seamless integration and rapid qualification supported by its familiar architecture, the HC555 is a drop-in solution for existing infrastructure.

Whether expanding capacity or optimizing operational costs, the WD Ultrastar 20TB DC HC555 20TB delivers unmatched efficiency, performance, and dependability for mission-critical storage applications.
