    I successfully installed AHCI driver on my 2006 Mac Pro running 64 bit Windows 7. I re-ran the Windows Performance Eval after the AHCI update. Interestingly, my disk score did not change: 5.9 prior to the update and the same after the update. My boot Win 7 drive is a 300gig Velociraptor drive (the drive is dedicated to Win 7).

    Can someone tell me why the disk score did not improve. I thought that changing from IDE to AHCI would lead to a substantial improvement.

    Thanks for a response.

    In slot 3. I just moved it to slot 2, re-ran performance index. Result was the same: 5.9 disk drive rating.

    5.9 seems to be consistent with what I've been seeing with faster SATA drives, so I don't think you'll get a higher score.

    What did you want, an 11?

    5.9 is the max on Windows squirrely scale.

    Next time try a read/write speed check before & after.

    16 SSDs in a Raid would also score a 5.9.

    Yep. RAID won't change anything as to the score, when a single drive can achieve a 5.9. ;)

    Testing drive througputs give a much better picture (AJA Speed Test for example).
