I have just purchased my first NAS and I am using 2 X 4TB WD Red (standard version, not the Pro model) drives within it. Maybe I have become a little too accustomed to the relative silence of SSD drives over the years as the noise from the WD Red drives I have seems a little louder than I was expecting. The router and NAS is located in the bedroom so if any read / write activity is taking place during the night, the noise from the drives is quite audible.
I have taken a video to demonstrate the noise I am referring to. The video is a fresh power on of the NAS and you should be able the hear the noise I am referring to from the 20 second mark onwards. I also recorded the noise level during a file transfer from my laptop to the NAS?
Is the noise level normal or have I been sent two drives that resemble a couple of dot matrix printers
Can some one help me for following similar question:
I have bought new Synology DS218j and two WD Red 4TB drives and used as Hybrind RAID (SHR). The problem is the vibration type sound, which happens in every 5 seconds despite that there is none of the two Disk LEDs blinking i.e. I do not use any data from the NAS drive at that time. For example while in night time the sound is quite audible
Initially I thought the problem is in Synology DS218j device but I thought to do following tests before I sent the Synology DS218j device for replacement:
By removing both the drives and then powering on the Synology DS218j and there was no such noise present.
After that I fitted only one of those 2 HDDs and such sound was audible again.
After that I fitted only second HDD (as single HDD) and such sound was audible again.
I consulted Synology DS218j chat support and they kind of gave me a hint that this is issue in WD Red since 2015, after suggesting me to do above tests, which I had already done.
