Product information

Description

Western Digital Ultrastar DC HC555 is a 3.5" internal HDD designed for enterprise and data centre applications that require very high capacity and continuous operation. This 20 TB drive features a 7200 RPM spindle, 512 MB buffer and a SATA III interface, combining large storage density with technologies intended to minimise power consumption and maintain reliable performance in multi-drive systems. The drive is helium-sealed to reduce internal friction and thermal load, and incorporates vibration and shock mitigation systems plus a projected 2.5 million-hour MTBF for long-term serviceability.

Advantages

The Ultrastar DC HC555 provides high capacity per bay while keeping power and cooling demands low through helium fill and energy-assisted magnetic recording. A triple-stage actuator improves track precision for higher areal density, and built-in rotation vibration sensors and multi-axis shock detection help preserve performance in dense server enclosures. Proven hardware and firmware designs enable straightforward qualification and integration into existing infrastructures.

Suitable for

Enterprise and hyperscale data centres requiring high-capacity nearline storage
Archive and cold storage systems where density and low power are priorities
High-capacity server and workstation storage pools for backup and large datasets
Storage arrays and JBOD enclosures with multi-drive configurations

Key specifications

Capacity: 20 TB
Form factor: 3.5 inch
Interface: SATA III (6 Gbit/s)
Spindle speed: 7200 RPM
Cache / buffer: 512 MB
Average weight: 0.69 kg
Designed reliability (MTBF): 2,500,000 hours
Helium-sealed internal environment for reduced power and thermal load

How to use

Install the Ultrastar DC HC555 into a compatible 3.5" drive bay or carrier and connect it to a SATA III port on the host controller. Ensure the system firmware and RAID/host controller support high-capacity drives and that any required drive configuration or firmware updates are applied according to your server or storage vendor guidance. In multi-drive arrays, allow sufficient airflow and observe manufacturer-recommended spacing and vibration mitigation measures to maintain optimal operating conditions.

Usage recommendations

Use this drive for nearline and cold storage workloads, large sequential throughput tasks and consolidated archival systems. For mixed or high IOPS workloads, validate performance in your intended configuration and consider appropriate RAID levels and caching strategies to meet availability and rebuild objectives.
