Synology Diskstation DS1010+ and DX510 Expansion unit review

We take the issue of noise very seriously at KitGuru and this is why we have built a special home brew system as a reference point when we test noise levels of various components.

Why do this? Well this means we can eliminate secondary noise pollution in the test room and concentrate on components we are testing. It also brings us slightly closer to industry standards, such as DIN 45635.

As this can be a little confusing for people, here are various dBa ratings in with real world situations to help describe the various levels.

KitGuru noise guide
10dBA – Normal Breathing/Rustling Leaves
20-25dBA – Whisper
30dBA – High Quality Computer fan
40dBA – A Bubbling Brook, or a Refridgerator
50dBA – Normal Conversation
60dBA – Laughter
70dBA – Vacuum Cleaner or Hairdryer
80dBA – City Traffic or a Garbage Disposal
90dBA – Motorcycle or Lawnmower
100dBA – MP3 player at maximum output
110dBA – Orchestra
120dBA – Front row rock concert/Jet Engine
130dBA – Threshold of Pain
140dBA – Military Jet takeoff/Gunshot (close range)
160dBA – Instant Perforation of eardrum

Noise was measured from half a meter away.

The system is very quiet and in a virtually silent room you can hear the fan noise, but only very slightly. In any ‘real world’ conditions the fan noise would not be noticeable, and within a business oriented server room the noise would be masked totally.

We measured power from the socket with 2 x 1TB Samsung HD103SI hard drives installed.

The system only uses 27 watts when the hard drives are in hibernation mode, and under load this rises to 56 watts with our dual configured drive array.

Time to test the cooling system. Our room ambient temperatures are 23c which is a reasonable temperature for most people to work and relax within.

The drives remained between 2 and 6 C above ambient with average results recorded above. The cooling system is extremely capable.
