Drive Acoustics and Power Consumption
Drive acoustics can be a very important metric when purchasing a drive. As such, we purchased, and built, a 12 x 12 x 12 box out of 2" thick insulating foam. In the center of the box, we placed the drive on 3" acoustic foam. Sound level measurements were taken from a distance of 6 inches.
Here, we have all drives hovering between 32 and 35 dba, throughout most of the testing. At the peak, the WD Black takes top honors as the loudest drive at 40 dba. Next in line, we have the Toshiba at 37 dba, and the WD Red, and Barracuda .14, round out the chart.
Our custom power testing samples each drive for a period of three minutes, across each workload. In order to offer more granularity, we sample the power in one-second intervals.
Across our entire workload, it is obvious that the WD Black is the top dog, eating up 8.5 watts at peak. The Toshiba manages five watts during random workloads, to a peak near six watts for sequential.
