I'm looking for a quiet and cool NAS system?

Dear Rob, I would like to ask your help with the following question. Currently, I have a Synology DS420j with four WD82PURZ disks in SHR2/RAID6 mode. The problem is that this setup is very noisy, and it produces a lot of heat. I should add that the NAS is in a tiny place with little ventilation. Earlier I had a DS220j with two WD40PURZ disks, and it worked like a charm. I replaced the disks with WD82PURZ models due to increased storage requirements. It was noisier, but the temperature remained below 43 degrees. In comparison, the current configuration is much louder, and at full speed, the two fans could only cool the disk to 47-48 degrees. I would like to ask what I need to change to have a quiet and cool system. I read about BeQuiet! and Noctua quiet fans. So far, I have chosen purple WD drives to eliminate frequent head parking. A two-bay NAS system with 10-12TB of RAID1, one gigabit Ethernet, and 5400 rpm drives are enough for me. I’ve only had Synology devices, but I don’t stick to the brand. I really appreciate any help you can provide. Best Regards, Chris

If you are recording surveillance then Purple drives make sense, but otherwise Red drives would be a better choice allowing hibernation when no one is accessing the data. They also spin slower and therefore generate less noise and heat.

The other option would be to create two RAIDs. Or one disk on its own for surveillance. This way other drives could rest when this drive do all the hard work.


I hope this helps.
