HDD Hard Drive Anti Vibration Screw Kit 8 PCS Blue

First off: Don't expect it to perfectly fit your case. Also, don't expect the screw to perfectly fit your item. Just accept it. Every case I've owned has had a slightly different implementation, and so if you are afraid to drill a hole or stop by your local hardware store for a few screws, then just deal with what you have or purchase something directly from your case manufacturer. I can't take stars off for that because I feel that's par for the course.There's two main reasons you might be looking at these:Noise issuesVibration, most importantly rotational vibration of a hard disk in a serverIf you are using multiple drives in the same cage or hot swap as part of a raid array and you want to most importantly minimize vibration, then I'm sure you've read all the conflicting info on the web. However, its clear that rotational Vibration effects seek times, hdd life, etc. and the problem gets larger the more disks are moving simultaneously. This is why WD Reds for example don't recommend more than 8 disks in an array simultaneously... they want you to splurge for more expensive enterprise options with better tolerances. It's a bit of a vague subject however and there's little direct technical information or accepted practice. I had to do quite a bit of digging and my own research to settle on the right solution. The reduction of noise does not necessarily mean the issue of vibration is mitigated, or is being dealt with properly- so I couldn't use that as a sole indicator.At the end of the day if you are looking to protect Enterprise or NAS disks in a home server or raid array, I would stick with these Akust items, either these or the 16 PCs purchasable here:  Akust HDD Hard Drive Anti Vibration Screw Kit 16 PCS Blue These are the grommets I chose to utilize in my own system after trying a half dozen of different vendors from amazon. They are rebranded E-A-R Grommets (View their website for a bunch of data sheets, info and graphs explaining their function). An important giveaway is the screw shape and the distinct blue color. Silent PC website also has review of these from some time ago. When you have these and the other common knock-off in your hands the quality and material differences are immediately apparent. Also, the black and other color variants have distinguishable marks from the manufacturing process that are not visible on the EAR grommets. I've attached a picture so you can distinguish better the EAR from the Lamptron, Silenx, Lian Li and other cheap rubber look alikes.Will it save my hard disks? I'm not sure. But I can quantify the differences in latency and performance under load in a raid array on a ZFS server (not huge, but definitely apparent- your mileage may vary depending on a variety of factors). That's enough for me to justify a $10-$15 investment. Makes me feel a little bit better about using Hitachi SATA disks as opposed to SAS disks with higher NRE.Hope it helps those on the quest to minimize server chassis disk vibration!Read some of the EAR info here: [...] There's a variety of other articles they have released that you can dig up from a quick google search.

When I received these, I had high hopes they would greatly reduce the seek vibration of the traditional hard drives in my new computer build. The blue collars are made of a very-squishy gel-like material and I can imagine they would help a lot with isolating vibration from hard drives. They even have little notches that allowed them to slot in perfectly into removable sled/carriers for my computer case.Unfortunately, even with the screws tightened down as far as they can be, the screw heads are a tiny bit too tall for the tolerances in my computer case. The removable carrier can't be re-inserted into the drive bay with the screws in.If you're mounting hard drives to a standard cage, without sled/carriers, you'll likely have better luck, but I unfortunately couldn't make these work in my build. Still a good product, just not right for my current case.

How well these work depends on your purpose and setup, I think. I'm a novice with computer hardware. My first mistake was buying a cheap, noisy hard drive. Do these silence it? No. Do these make it quieter? Somewhat, yes.I had to use a drill to expand the hard drive mounting holes in my computer case. I started with a 5/32" bit and slowly went up in size to 1/4".I don't think the product is really faulty at all; I was just wrong to think it was a magic bullet. Maybe if I had started with a quieter hard drive, it could have been whisper quiet with these.EDIT: Installing these may or may not have contributed to my hard drive failing a few days later. The price and the month-long shipping time seems less and less worth it.

Fit well

I bought these so I could add a third drive to my Fractal Meshify C case that I'm using for my NAS build. Other than the hexagonal grid on top of the case being slightly misaligned (nothing a wire cutter and some micro files couldn't fix), these worked perfectly for hanging a drive from the top of my case.I'll be designing a 3D printed sled that can create a modular stack so multiple drives can be added as well.

Buyer beware! These are a complete waste of money. Did not make my hard drive any less noisy. With all the time and trouble it took to get them in place it was a HUGE disappointment once we got our computer back together only to find it did absoultley nothing.

So I have a very noisy boot drive. I bought this product in hopes that it would reduce the vibration. The problem is, the screws are too bulky - I could not slide the drive back into its bay! Oh, well. Maybe vibration is good for my mind....
