Power Consumption

The WD Red 4TB idled at 4.0 W while 6.2 W was consumed during seek activity, which is right in line with its little brothers, after accounting for the 4TB variant's extra platter. Interestingly, the WD Green's headparking feature, absent in the 1TB and 3TB Red drives, makes an appearance here, unloading after 7~8 seconds and shaving off 0.8 W. The Se 4TB used twice that amount at idle and almost topped 10W when seeking. It's still not bad for a 4TB 7,200 RPM drive.

Acoustics


The Red 4TB wasn't as quiet as the smaller versions, though the type and character of noise was similar. Sitting idle, it produced a soft, innocuous whooshing which measured 15 dBA@1m. Seeks were produced in a slightly scratchy pitter-patter pattern that was so muted that the SPL increased to only 15~16 dBA@1m. Altogether the sound is pleasant — only the most sensitive listeners will find fault with it.

The Se 4TB measured only 1 dB higher at idle as it had a similar sound but with hint of buzzing. Its seeks seemed to be lower in frequency, sounding less distinct to the ear, but they had a heavier, thumpy character. It's definitely a louder model overall but the noise lacks any truly negative characteristics.

Low frequency tonal peaks were detected at 90 Hz and 120 Hz on the Red and Se drives, confirming their rotational speeds of 5,400 and 7,200 RPM, respectively.

On our subjective vibration scale, two of WD Red 4TB samples scored an 8 (very good) while the other two scored 9 (excellent), indicating some sample variation. Both of our WD Se 4TB samples scored a 7, which is about average for a typical desktop drive these days.

Taking this into consideration, we rank the Red 4TB just below its little brothers while the Se 4TB finishes ahead of 2TB 7,200 RPM models form Seagate and Hitachi and slightly behind the Barracuda 3TB.
