[Qutestion to WD Staff] What are specs of this HDD - revolutions per minute


#1

Hello

I’m interested in this hdd but I can’t find information on it’s revolutions per minute in spec and info on the internet either says 5400 or 7200.

so which one is it?

-mystiq.

Here is the datasheet for WD Caviar Green Desktop Hard Drives:
http://www.wdc.com/wdproducts/library/SpecSheet/ENG/2879-701229.pdf

The rotational speed is listed as “IntelliPower”.

This marketing speak clouds the specification, but AFAICT the actual speed is 5400RPM.

A competitor’s document shows that the sustained transfer rate of 109MB/s is about 10% less than that of a current model 2TB 5900RPM drive (121MB/s).

7200 RPM according to WD’s spec sheet, was just looking for this myself!
