Benchmarks - Power Consumption and Acoustics
Our power consumption testing involves running the power supply from the NAS through the output on our Kill-A-Watt meter. Results are recorded at several intervals including Idle, peak and after the drives enter standby.
Above, we have our results from the power consumption testing. The first thing to note here is the use of WD Black drives and as we all know they use a bit more power. Peak power consumption during workload testing was 53 watts, after an idle period the Drobo dropped a few watts down to 47. Finally the drives entered standby and we had a power reading of 22 watts.
Acoustics are measured from a distance of one foot with our IEC Type II Sound Level Meter.
Upon initializing the 5D, we measured a peak fan noise of 31.9dBA. After the drives spun down, we noted an idle noise level of 29.5dba.
