I would definitely recommend skipping any current large WD drives for home use. < 6TB are SMR and problematic in a NAS, and 6TB+ have a very irritating noise that no-one seems to be able to diagnose (sounds like a scanner when idle). I bought some 8TB WD Golds, and I was expecting them to be louder, but they do something very weird when idling and it's an extremely penetrating sound. It seems to be present on most large models: https://community.wd.com/t/strange-noise-coming-from-10tb-dr...
