Product information

Description

Western Digital Ultrastar DC HC555 18 TB is a 3.5" SATA III internal hard drive designed for 24×7 multi-user data center and enterprise environments. With 18 TB capacity, 7200 RPM spindle speed and a 512 MB buffer, the drive uses proven Ultrastar hardware platforms, Triple-Stage Actuator (TSA) and HelioSeal® helium technology to deliver high density, low power consumption and dependable performance for intensive workloads.

Advantages

The HC555 combines field-proven components and modern technologies such as energy-assisted perpendicular magnetic recording (ePMR) and TSA to increase tracks-per-inch and enable higher capacities while keeping power use low. HelioSeal reduces internal turbulence and contributes to one of the lowest power profiles in its class. Built on a widely deployed Ultrastar platform, the drive offers rapid qualification and integration for existing systems and a projected MTBF of 2,500,000 hours for reliable operation.

Suitable for

Enterprise data center storage
High-density archival and nearline storage
Multi-user 24×7 workloads
Backup, large-scale file repositories and object storage
