I bought my Synology DS-1019+ a couple of years ago and although it's worked perfectly, I've always been a little miffed as to how loud it is. Not the drives spinning, accessing or the fans but just a general vibrating buzz type of noise. If I put pressure on the case, the noise would reduce or change. It's always been there, some days it was louder than others. I've got it on a foam bed with noise cancelling feet and extra pads. None of these really made any difference.

Yesterday, I shut it down, removed all the caddies one by one and put pads of sticky velcro (the soft side, not the hard rings) along the side runners and also inside the caddy in a couple of places where the drive touches the plastic.

Here it is on the side runners.

When I powered the NAS back up, I could instantly tell that it's better. I can still hear the drives spinning quietly and the access sounds but the vibration and buzz appears to have gone completely. It's so different, so much better.

I can't claim responsibility for this, I found it somewhere on line and I thought it worth sharing here.

If you've got a Synology (or probably any NAS) with hard drive vibration sound, this is a really simple, easy, cheap solution.

I've not found my DS1618+ to be noisy but it has plastic drive trays rather than metal. Identical design though.

These drive trays are plastic as well.

I've found isolating the fans from the back panel can also help. I've used the rubber isolators that come with some fans or disk isolation washers between fan and back panel.

I've never had a problem with fan noise, it was always the vibration that annoyed me. Now all I can hear is the drive heads seeking which is a significant improvement.

One method I've used was to isolate the NAS from the storage its in. I placed some small cut sponges under the feet of the NAS so that it vibrates on the sponges and thus less of it is transferred to the storage and echoed out. It won't help with all sources of sound in a NAS but will help in an instance where HD in a NAS vibrates the whole NAS casing into the storage it sits on.

Yes, I've effectively done this as well, I replaced the standard feet with AcoustiFeet Anti-vibration Case Feet, it's sitting on BJADE'S Anti-Vibration Isolation Rubber Pads and a layer of vibration absorbing foam but although they stopped vibrations rattling the shelf it's on, they did nothing to stop the vibrations within the unit itself.

I guess this is one of the flipsides of toolless parts. Had it been caddy-less and you had to fix the drives to the chassis then it'll very likely not rattle.

Aye that's exactly it. I don't think it's the drives rattling against the caddies themselves but I put some pads there anyway, I'm pretty sure it's all the caddies vibrating against the cage they mount in. When I put them back in with the velcro, they're noticeably a bit harder to push back in place but still lock back in nicely positively.

Do these just slot in on a plastic rail? My old PC tower has toolless drive cages and they have a rubber bit that goes over the screw to slide into the cage. Bit hard to describe without a picture, but I know they fit really snug so no chance of any wobble.

There's a rubber bit inside where the drive goes in the caddy but no, where the caddy slides into the cage, there's nothing. You can see from the pictures above where I've added the velcro. It's no wonder they rattled.
