Our take on the Western Digital Ultrastar DC HC560 20TB 3.5" Internal Hard Drive

The Ultrastar DC HC560 is Western Digital's 20TB enterprise helium-filled hard drive, built for always-on storage in servers and NAS arrays. It uses nine shingled platters with OptiNAND flash-assisted firmware, spins at 7200 rpm and carries a 256MB cache. This SAS 12Gb/s version is aimed at data centers and workstations with an SAS controller, not at typical home desktops, which use SATA. It competes with Seagate's Exos X20 and Toshiba's MG10 on capacity and sustained throughput, and owners praise its reliability in multi-drive arrays while noting the noise and heat of a 7200 rpm enterprise drive.

Pros
  • 20TB per drive in a standard 3.5-inch bay
  • Helium-sealed design keeps power and heat down for its class
  • 256MB cache and 7200 rpm give strong sequential throughput
  • OptiNAND firmware improves metadata handling and drive health
  • Built for 24/7 duty in multi-drive systems
Cons
  • SAS interface needs an HBA; it will not plug into a SATA port
  • Audible seek noise and vibration in desktop use
  • Shingled recording means slower random writes than conventional drives
  • Runs warm; needs airflow in dense enclosures
  • No consumer warranty support channel; enterprise RMA process

What reviewers say

Owners of the HC560 series report low failure rates across large drive pools and steady sequential speeds. Most criticism centers on noise, heat and the SAS-only connection rather than reliability.

What people mention
  • ReliabilityPraisedOwners in large drive pools report few failures over years of continuous use.
  • NoiseCriticisedSeek chatter and idle hum are noticeable in desktop and home NAS setups.
  • HeatMixedHelium helps, but the drive still runs warm and needs airflow in dense enclosures.
  • InterfaceCriticisedThe SAS connector requires an HBA and will not work on a standard SATA port.
  • SpeedPraisedSequential transfers are strong for a hard drive, though random writes are slower due to shingled recording.

Questions and answers

Will this drive work in a regular desktop PC?
Only if the PC has an SAS controller card. The drive uses a SAS 12Gb/s connector and will not fit a standard SATA port. Most home users should look for the SATA version of this drive.
Is it good for a home NAS?
It works in a NAS that supports SAS drives, and the 20TB capacity suits large media libraries. Check that your NAS lists SAS support and has enough airflow, since the drive runs warm and is audible.
How does it compare with the Seagate Exos X20?
Both are 20TB helium enterprise drives at 7200 rpm with similar sequential performance. The Exos X20 is also sold in SATA and SAS versions, so pick whichever interface your system supports and compare warranty terms.
What is OptiNAND?
It is flash memory built into the drive that stores metadata and helps the firmware manage the shingled platters. WD says it improves performance and drive health monitoring; it does not act as a cache for your files.
Does it need special mounting or cooling?
It fits standard 3.5-inch bays. Because it is a 7200 rpm enterprise drive, give it direct airflow and avoid stacking many drives without ventilation.
What is in the box?
The drive itself. Screws, cables and a controller card are not included, so plan for an SAS cable and HBA if you do not already have them.
Where is the Western Digital Ultrastar DC HC560 20TB 3.5" Internal Hard Drive cheapest?
At Newegg, for $1,144.45, as of our latest check.
