WD Ultrastar DC HC560 Spec and Price in France
The HC560 is the 20TB generation of WD's data-center nearline line, adding OptiNAND to the helium-sealed 7200rpm platform: a 512MB cache and a five-year warranty, per the WD data sheet. Sustained throughput reaches 291 MB/s — near the ceiling of SATA hard-drive mechanics — and the workload rating is the enterprise 550TB/year. It is CMR at nine platters, and the price per terabyte is what makes data-center storage economical.

What owners and reviewers say
Summarised from 1 source(s), reviewed September 14, 2026. A source is counted only where it names this model exactly. How we track prices
Commonly praised
- Reviewers confirmed the vendor's claimed sustained transfer rate in benchmark testing, measuring sequential reads and writes just under the rated figure.
- It posted the strongest workload results the reviewer had recorded for a hard drive in the file-server, web-server and workstation profiles.
- It layers a flash-enhanced metadata architecture, energy-assisted recording, a triple-stage actuator and helium sealing, and carries a five-year warranty.
Commonly criticised
- It is expensive at its asking price.
