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.

60dBA – Laughter
70dBA – Vacuum Cleaner or Hairdryer
80dBA – City Traffic or a Garbage Disposal

Noise was measured from a meter away.
The RS212 is generally relatively quiet, with the three small fans spinning very slowly. Placing a heavy data load on the two drives raises the ambient temperature of the chassis and the fans spin up to compensate. The noise emissions peak at 34.5dBa which might be a little loud for a bedroom environment. The RS212 is designed however for use in a small business, which would assuredly have a dedicated IT room.
We measured power from the socket with 2 x 500gb Samsung hard drives installed.
When idle, the power consumption hovers around the 12 watt mark, rising to 23 watts when both drives are active writing data. RackStation devices generally tend to consume a little more power than the DiskStation products, especially when idle.
Good results, although a few degrees higher than some of the DiskStation products we have tested in recent months, due to the confined shape of the chassis and use of small fans.
This is too slow, are you going to review the 812? I want a review of that please.
We have this in our office and it has worked well now for a week, too early to report on the life span, but most of these last many years and are designed to deal with humidity and high temperatures, even blocked fans!
nice looking NAS, not ideal for my new purchase however, due to the shape. hope to see more consumer models on Kitguru soon
