I’m guessing the only fix is to get quite drives and if so are there ones that for sure would be?
I’ve just started setting up my new DS1821+ with 5 of the Synology HAT5300-12T drives and they seem to be a lot louder then my old DS1813 with WD WD40EFRX 4TB drives. The WD drives do make noise but nothing like the Synology HAT5300-12T drives.
I don’t think its the fans and they are already on the lowest speed setting.
There is a loud clunk randomly every few secondsminutes and there is a loud hum whenever the DS1821+ running. I can even hear the drive head movement (clunking) in the other room. I never really notice the DS1813 with WD drives. If it was just the head clunks maybe I could live with it but the hum in my ears is too annoying.
Is there a quite mode for the drives?
Will it break the array if I try running the DS1821+ with one or two drives to see if there is a bad one? Was also wondering what would happen if I moved the 8 WD drives into the DS1821+ to see if the hum was still there and see what the read/write performance was over the 10GE network.
It took about 3 days to copy everything from the DS1813 to the DS1821 and I’m not looking forward to doing it again and losing the money buying another set of drives if I can even find them.
I liked the idea of getting Synology drives and the 5 year warranty but am very disappointed. Maybe the HAT5300 should only be sold for rack mounted devices in a server room.

The HAT5300 doesn’t even list Acoustics but vibration so I guess they are loud.

MiB? Really?

The old DS1813 with the WD WD40EFRX is much more quiet but the online specs say 25dBA idle, 28dBA seek. ???

I got some WD Red Plus WD140EFGX to try out and they do much better with head seek but the flippin’ hum is still there. If its all 7200RPM drives I don’t know how they can be rated at 20dBA idle and or how people put up with it.
I see a few places list the 14TB WD140EFFX having 5400 RPM but in the WD specs it says that is just the firmware and the drive is really running at 7200 RPM.

I don’t think there are any 12-14-16TB NAS drives running at 5400 RPM.
I wish there would be some movement in 2.5″ or 3.5″ SSDs doe NAS. I don’t want to spend $800 of a 8TB drive just to get rid of the hum.
