Output Noise
For these measurements, we used a high-quality CEM-8852 Sound DB Meter that was installed 50cm away from the NAS. The ambient noise in our lab during noise measurements was close to 30dBA.
Output Noise Comparison Graphs
The following graphs show the output noise of the DS213+ in comparison to other units we have tested in the past.
The output noise of the DS213+ is relatively low during normal operation with two disks installed. Its noise level will, most likely, not bother anyone.
