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.
