The extra noise is fanspin when I held it directly against the back of the QNAP, I was moving my phone around the case during the recording.
Any of you got NAS drives to compare to?
This weird periodic scratching noise is what I'm mostly worried about.

Only does this so often if I'm actively copying something onto it, or if I'm browsing things in the file explorer and if opening a video file / seeking the timeline of it.
If this is normal noise I might just keep these. Still worried about long term use as I'm powering it off daily in the long run.
Is this normal?

QNAP TR-004 + 2x WD RED PLUS 8TB drives.
People keep saying this shit is normal, but idk.
The issue is that it also does this noise idle because of PWL. Rubber / low vibration stuff under it doesn't help as the noise is the major part of it.

TL:DR; please tell me if the noises these drives make is normal. Feels like thump+scratch.
I might just return all this and buy 4TB SSDs for the price...

Tiny room, no other place to keep it too. Please advise.
