Buying tip
Synology, QNAP, Asustor, TerraMaster and UGREEN list 8 Western Digital Ultrastar DC HC520 variants, but the high-capacity part numbers (above 12TB) tend to appear only on newer models. If you run an older or 2-bay machine, confirm your exact model on the drive page before ordering — a same-series part number is not always interchangeable.
