I excluded the noise from my hard disk drives (HDDs).
There are two types of noise. One is “crisp”, and another one is buzz. The crisp noise doesn’t bother me, but the buzz noise bothers me a lot. It comes from disks inside a HDD, so I excluded the noise by covering it.
This is what I used. Its name is Otonasheet, meaning silent and sheet.
Otonasheet is a rubber sheet which looks like lead. One sheet can cover two HDDs.
Put the sheet to my HDD.
…and wrap it. The sheet can be bended easily. The folded part breaks and falls into pieces.
The side is also need to be covered carefully.
Expose the connectors outside.
Don’t forget to put a label on it especially if you consist RAID. Write down at least the product number and the serial number.
This is a HDD bay. I recommend a PC case which has an unmountable HDD bay. Can you see the black tapes? Fix HDDs with these tapes instead of screws. These tapes are available at mountain sports stores. There are tapes made from cloth and rubber. You can choose whichever you prefer.
I attached HDDs.
Put the bay back. This excludes the noise a lot!
