tacoslammer Posted February 23, 2018 Share Posted February 23, 2018 (edited) Speccy Free Version 1.31.732 reports all my Hard Drive disks speeds as 10,000 RPM when they are actually 7,200 RPM per manufacture specs. See attached. Note both say: RPM/Buffer Size or Attribute = 10,000 RPM with 16 MB cache. The WD7502AEX reports Speed = 10000 RPM. The WD2003FZEX reports Speed = 7200 RPM. Both should report 7200 RPM in all four instances per WDC specs. and HDD Label. Edited February 23, 2018 by tacoslammer Complete information.

Moderators mta Posted February 23, 2018 Moderators Share Posted February 23, 2018 the RPM/Buffer field is most probably just a firmware 'note' field that the manufacturer has filled in wrong. I guess that is also happening to the Speed fields. Speccy isn't actually testing the RPM's, just passing on what is getting from WMI libraries.

tacoslammer Posted February 23, 2018 Author Share Posted February 23, 2018 Last week both HDDs reported a speed of 10000 RPM. This latest (today) Speccy report reported the correct speed of 7200 for one and 10000 for the other. That sounds like the WMI libraries have changed!!!

Moderators mta Posted February 23, 2018 Moderators Share Posted February 23, 2018 if Windows has updated in that time frame then Yes, very probable.
