Product information

Description

The Western Digital Ultrastar DC HC550 is an enterprise-class 3.5" internal HDD offering 18 TB capacity, 7200 RPM spindle speed and a 512 MB buffer. Designed for cloud and hyperscale data centers, this drive uses HelioSeal technology on a 9-disk platform and integrates Energy-Assisted Magnetic Recording (EAMR) together with a Triple Stage Actuator (TSA) to increase areal density while maintaining reliability and performance.

Advantages

The Ultrastar DC HC550 delivers high storage density in a standard 3.5" SATA III form factor, enabling drop-in replacement for large-scale Big Data workloads. It provides a lower total cost of ownership through reduced idle power per terabyte and improved mean time between failures (MTBF). The combination of EAMR, TSA and helium-sealed mechanics yields higher areal density and optimized operational efficiency for data center deployments.

Suitable for

  • Cloud and hyperscale data center storage
  • Mass data archival and cold storage
  • Enterprise servers and storage arrays
  • Big Data workloads and object storage

Key specifications

  • Capacity: 18 TB (18,000 GB)
  • Form factor: 3.5"
  • Interface: Serial ATA III (SATA III)
  • Spindle speed: 7200 RPM
  • Cache: 512 MB
  • MTBF: 2,500,000 hours
  • Weight: 0.69 kg

How to use

Install the Ultrastar DC HC550 in a compatible 3.5" drive bay with a SATA III connection. Ensure the server or storage chassis supports helium-filled enterprise drives and follow your system vendor’s guidelines for mounting, power and cooling. Format the drive and configure RAID or the chosen storage software according to your data center architecture and workload requirements.

Usage recommendations

For optimal reliability and energy efficiency, deploy this HDD in data center environments with appropriate airflow and cooling, use it as part of tiered storage or large-capacity arrays, and monitor drive health through vendor-provided tools and system telemetry.
