Comment on Looking for HW recommendations for DIY NAS/Homelab

I’m thinking 25DB is a hard cap, ideally under 20DB.

I think HDDs are typically around 5-10DB,

Um no. More like 20-25db at idle, up to 30 during heavy seek activity, depending on model.

I run 3x 5400rpm drives in my NAS, and the drives are definitely the loudest parts in the whole build, and are definitely noticeable in the office room.

Can confirm I am running what I am often is told is overkill here.

7200rpm hitachi 12TB drives

Just measured at 19DB at a meter away running a zpool scrub.

So it definitely depends on which HDD you have.

Really? I currently sit like 3’ from my current PC NAS, and while I can hear it, the fan noise seems louder (stock AMD heatsink and fan). This YouTube looks at very similar drives to what I have (my drives are WD 8TB NAS Plus 5400RPM, video is 8TB NAS Pro 7200), and the measurement is something like 10-15DB per drive. Mine should be quieter than the video, so I think it’ll be fine.

I’ll probably need to replace my drives soon since I got them 5 years ago (though they were off 80% of the time), so I may consider SSDs if the pricing looks reasonable (I’m only using 2-4TB right now, but I expect that to double or triple in the next couple years).

Anyway, this is a somewhat temporary situation. Quiet gives me options. If it’s too loud, I can keep it on my desktop. I’m more looking for lower power and smaller form factor (current one is a massive ATX tower).

  It seems to be a relative measurement, and so the values look to be 10-15dB above ambient, not the absolute dB of the drives. You can see he subtracts the background dB from the spl meter early in the video.
