Extended Product Information

FAQs

Is this drive compatible with consumer PCs?

Yes, it uses a standard SATA interface, but it is physically larger and louder than typical consumer drives and is optimized for server-grade cooling and vibration handling.

What is the warranty period for this drive?

The Western Digital Ultrastar DC HC555 comes with a 5-year manufacturer's warranty.

Does this drive support hot-swapping?

No, this model is not designed for hot-swap functionality.

How loud is this hard drive during operation?

As an enterprise-class 7200 RPM hard drive, it is louder than standard consumer drives and is intended to be used in chassis designed for sound and vibration dampening.

Does it require a special controller?

No, it uses a standard Serial ATA III interface which is compatible with most modern motherboards and RAID controllers.

What is the power consumption?

The drive has a typical power consumption of 6.4 W and an idle consumption of 5.3 W.

Troubleshooting

Drive not detected by BIOS/OS

Check the SATA data and power cable connections, and verify that the SATA port is enabled in the motherboard or RAID controller BIOS.

Performance slowdowns during heavy use

Ensure the drive is not overheating and that the enclosure has sufficient active airflow; check for high levels of ambient vibration.

Pros and Cons

Pros

  • Industry-leading 20 TB storage capacity
  • High reliability with a 2.5 million-hour MTBF rating
  • Energy-efficient operation via HelioSeal technology
  • Advanced vibration protection for multi-drive setups
  • Fast 7200 RPM performance with a large 512 MB buffer

Cons

  • Not intended for typical consumer desktop use
  • Requires proper airflow due to enterprise heat output
  • Higher power consumption compared to lower-capacity consumer drives

Setup, Compatibility & Care

This drive uses a standard Serial ATA III interface, making it physically compatible with most 3.5-inch drive bays. When installing, ensure the host system provides adequate cooling, as enterprise drives perform best within a controlled thermal range of 5 to 60 °C. Because the drive is rated for 24/7 operation, it should be kept powered on; frequent start/stop cycles are rated for 600,000 cycles, but constant uptime is its intended state. Always ensure your server's backplane supports SATA III speeds of 6 Gbit/s to fully utilize the sustained transfer rates of the drive.
