DNS-323 power consumption - updated results

Regarding the electricity consumption discussed a bit off topic in this thread:

I re-ran the tests described below, but this time with a proper inline AC Amperemeter and got these results:

Code:

Unit turned off:                       1.1 watts
Unit turned on, drives spinning idle: 22.2 watts
Unit turned on, drive heads seeking:  24.4 watts
Unit turned on, drives not spinning:  10.4 watts

The original test with cheap watt meters:

Today I tested the power consumption of the above setup (two Seagate 500GB 7200 RPM drives).

Code:

Unit turned off:                       6 watts
Unit turned on, drives spinning idle: 26 watts
Unit turned on, drive heads seeking:  29 watts
Unit turned on, drives not spinning:  14 watts

The results were measured with two different consumer-grade (cheap) watt meters at the wall, and the numbers where averaged. I live in a 230 volt country.

Note: The results may be a watt or two off compared to the standard DNS-323 because I installed a bigger fan.

If you want to know how much it costs you having the DNS-323 turned on 24/7 (or for shorter periods) with or without using drive spin down, you can use this Javascript power cost calculator.

The ones I have are Chinese OEM products branded with local names like "Sartano". One of them had the actual maker printed on the back, though: "Cixi Yidong Electronic Co.,LTD".

But that exact model won't be available in all countries. Look instead in DIY or electronic shops for similar products.

This one looks exactly like my "Sartano" but with an Australian plug.
