Our take on the Western Digital Ultrastar DC HC555 3.5-inch Internal HDD 16 TB 7200 RPM

The Ultrastar DC HC555 is Western Digital's 16 TB enterprise hard drive, built for data centers and heavy NAS use. It spins at 7200 RPM and uses conventional magnetic recording with a large cache, so it delivers strong sequential throughput for backups, archives and media libraries. It is a helium-sealed, 3.5-inch drive that runs cooler and quieter than older air-filled high-capacity models. Compared with desktop drives like the WD Red Pro or Seagate IronWolf Pro, it targets 24/7 workloads and multi-drive arrays rather than a single home PC.

What reviewers say

Owners of NAS boxes and servers rate the HC555 line for reliable capacity and steady throughput. Most criticism centers on noise and the need for proper cooling rather than on failures.

What people mention
  • NoiseMixedOwners say it is quieter than older enterprise drives but still audible in a quiet room.
  • HeatPraisedHelium sealing keeps temperatures lower than air-filled drives of similar capacity.
  • ReliabilityPraisedLong-term NAS users report few failures under continuous operation.
  • PerformancePraisedSequential reads and writes are fast for a spinning disk, suiting backups and media.
  • FitMixedStandard 3.5-inch mounting works, but dense arrays need vibration damping.

Questions and answers

Is this drive good for a home NAS?
Yes, if your NAS supports 16 TB drives and you want bulk capacity for backups or media. It is built for 24/7 use, but check your enclosure's drive compatibility list first.
How does it compare with a WD Red Pro?
Both are 7200 RPM helium drives aimed at arrays. The HC555 is an enterprise line with data-center firmware, while the Red Pro is tuned and warrantied for NAS use with consumer support.
Can I use it as a desktop boot drive?
It works, but it is a poor choice for an OS drive. Random access is far slower than an SSD, and the drive is noisier than desktop models.
Does it need special cooling?
It runs cooler than older high-capacity drives, but dense multi-drive enclosures still need airflow. Keep it below the manufacturer's rated temperature.
What is in the box?
The drive itself. Screws, cables and mounting brackets are not included, so check what your case or NAS tray provides.
Is it compatible with my RAID controller?
Most SATA controllers handle it, but confirm your controller and backplane support 16 TB drives and the drive's sector format before buying a full set.
Where is the Western Digital Ultrastar DC HC555 3.5-inch Internal HDD 16 TB 7200 RPM cheapest?
At Newegg, for $941.00, as of our latest check.
