Choose Between 5400 and 7200 RPM for a NAS

Quick answer

In WD's Red Plus sheet the slower drives are the small ones: the 2TB, 4TB, 6TB and 8TB models spin at 5400 or 5640 rpm and the 10TB and 12TB models at 7200. The slower group idles at 2.4W to 4.1W and 21 to 25 dBA; the 7200 rpm group at 2.9W to 6.1W and 20 to 34 dBA. Speed is not the whole answer, though: the 7200 rpm WD120EFBX is listed at 20 dBA idle, quieter than the quietest slower model, the WD20EFPX at 21 dBA. Every WD Red Pro on WD's sheet is 7200 rpm.

What the figures say, and one footnote

The spread inside the 7200 rpm group is wider than the gap between the groups. Its idle noise runs from 20 to 34 dBA and its idle draw from 2.9W to 6.1W, depending on the model number. Two drives of the same capacity and speed can sit at opposite ends, so compare model numbers, not speeds.

WD attaches a footnote to the WD120EFGX: its spindle turns at 7200 rpm although the drive may report 5400. A tool that reads the reported value will show the wrong class for that model.

For WD Red Pro, WD's sheet lists 21 models from 2TB up, all at 7200 rpm, with idle noise of 20 to 34 dBA.

Where the figures come from

Western Digital's WD Red Plus product brief and WD Red Pro data sheet, read on October 12, 2026. Each figure is the one printed beside the model number. Other makers' lines are not in the comparison because their power and noise rows have not been read into this site's record.
