Problem with the Primary disk score in Windows Experience Index scoring to low
Posted on 2011-03-22
I am using the Windows 7 Windows Experience Indox (score 1.0 to 7.9) on some i7 desktops I built.
The issue is the Primary Hard Disk subsore is 5.9 no matter what I do with my SATA hard drive.
I started with SATA 2 (3 Gbp/s) SATA Drives on a i7-920 Gigabtye desktop. Ran the test and the score was 5.9 for Primary hard drive. Then I replaced the primary hard drive with a Western Digital Caviar Black SATA 3 (6 Gbp/s) hard drive (the fastest SATA hard dirve and ran the Windows Experience test. The score stayed at 5.9.
It seems this is not reporting correctly. I can tell a huge speed increase since going from the Western Digital SATA 2 to the SATA 3 so I know it is much faster.
Anyone know why this is happening?
I ran the 3rd party PassMark Performance test on the i7 desktop and the Disk Mark is 706 out
of 800 which is good.
I have done this same type test on two diff. i7 desktops (one an i7-950) with exact same type results.
Both dekstops have 8 GB of DDR3 RAM, plenty of hard disk space and clean installs etc..
Anyone know if the Win 7 perf. test for hard drives is broken in this way?
