Power Consumption

The 5K3000 consumes almost the same amount of energy in operation as the EcoGreen F4 which is admirable given its higher rotational speed. The Barracuda Green uses 0.5W more when idle and 1.7W more seeking. Lor low power server operations, the WD Green WD20EARS is still king, with just 2.8W at idle.

Noise



The Deskstar 5K3000, idle and seeking.

Like many other sub 7200 RPM drives, the 5K3000 is very quiet measuring 14~15 dBA when idle and 15 dBA when seeking at one meter distance. Its acoustic profile is very soft with a benign hissing character. When seeking, the drive lacked the sharp clicks and hard thumps of noisier drives so it's no surprise that we measured almost no SPL difference between seek and idle. Automatic Acoustic Management (AAM) is not supported but there is no point, as it only affects seek noise.

As for the rotational speed, we measured a fundamental tone at ~98 Hz, which works out to 5880 RPM, 60 RPM off its 5940 RPM specification.

Our sample had a moderate level of vibration similar to the EcoGreen F3/F4. It is a little high for a "green" drive but not surprising given the design of its casing. Acoustically it was slightly louder than the F4, but only when idle. The WD20EARS remains unchallenged when it comes to noise.
