Question about Red Plus - 391487
Is the HDD completely "silent" for someone? For me, it has very little vibration, but every now and then it makes click noises. When copying large files, you can (currently) hear almost nothing. But when I install an app/S.M.A.R.T. on the NAS or the system simply idles, the noises come. They are amplified by the Synology enclosure (ds720+). Normal?

This is completely normal. This can be explained by the way an HDD works, because the read/write head of the HDD has to "jump" to reach the corresponding sectors. So if you "read" or "write" different things at the same time, the head will have to jump back and forth faster or more often. Defragmenting helps if the sectors of a file are not in a row ... then the clacking may become quieter. But the
hard drive is still one of the quietest I have in my NAS.
