Product information

Description

Western Digital Ultrastar DC HC550 18 TB is a 3.5" internal hard drive engineered for high-capacity data storage in servers, NAS systems and enterprise environments. With 18 TB capacity, 7200 RPM spindle speed and a 512 MB cache, this SATA III HDD is intended for bulk archiving, backup systems and dense storage deployments that require reliable, high-density disk capacity.

Advantages

The Ultrastar DC HC550 provides very large single-drive capacity to reduce the number of drives needed for massive datasets and to lower rack space requirements. Its 7200 RPM design and 512 MB cache support sustained transfer performance for sequential workloads common in archival and backup tasks. The SATA III interface ensures compatibility with standard server and NAS controllers, while the drive’s design is targeted at enterprise-class deployment scenarios where capacity, reliability and efficient power use are important.

Suitable for

  • Cloud storage and hyperscale data center capacity expansion
  • Bulk data archiving and long-term retention
  • Backup targets and secondary storage systems
  • High-density NAS enclosures and server storage pools

Key specifications

  • Form factor: 3.5-inch internal hard drive
  • Usable capacity: 18 TB
  • Spindle speed: 7200 RPM
  • Cache size: 512 MB
  • Interface: Serial ATA III (SATA 6 Gb/s)

How to use

Install the Ultrastar DC HC550 into a compatible 3.5" drive bay in a server, NAS or storage enclosure that supports SATA III connections. Secure the drive mechanically according to chassis instructions and connect the SATA data and power cables to the host system. Initialize and partition the drive within the operating system or storage controller, then configure it as part of a volume, array or backup target as required by your storage architecture. For enterprise deployments, integrate the drive into existing monitoring and RAID or erasure-coding schemes to ensure data protection and operational visibility.

Usage recommendations

Use this drive in systems designed for high-capacity, always-on storage workloads. For best results, pair with compatible enterprise-class controllers and cooling arrangements, and include the drive in regular backup and monitoring routines to maintain long-term reliability and performance.
