How do the noise levels of WD Red Pro compare to those of WD Gold? I am considering primarily 6 TB drives with 7200 rpm.
According to a spec sheet, the WD Red Pro are 31–34 dB in idle/seek, while the WD Gold are 29–36 dB in idle/seek. But I don’t think you can look only at the dB; the characteristics of the sound must be weighed in as well, so any personal/anecdotal experiences here would be great.
I currently have 4x new WD Gold 6TB drives in a Synology DS918+ NAS. My WD Golds have a “high-treble” and raspy noise which is very unpleasant. They sound very scratchy, which I haven’t heard in internal hard drive since the early–mid 90’s. That alone makes me consider alternatives, e.g. why I’m wondering how the WD Red Pro’s are.
Since before, I also own HGST DeskStar 4TB 7200 rpm drives. While their noise is definitely discernible, they have a very muted and chugged sound which doesn’t annoy me, they sound like a boiling tea pot.
