    Thanks for this tip. It changed my Windows 7 score for my brand new hard drive from a somewhat worrying 2.9 to a 5.9. That’s quite a jump.

     Keep in mind that Windows Vista will only have a maximum score of 5.9. Windows 7 bumps that WEI score up to 7.9.

    Keep in mine that my SSD drives are faster than your hard drives… At least OCZ gave me stickers that say that… I have two OCZ vertex 3 drives in raid 0 that are getting 7.4 rating in windows 8 developer preview?

  • Vitalidex says:

    Rotary hard disks will NOT test above 5.9 in WEI.  Only SSD drives will go above 5.9

     No. It depends on the Drivers, windows uses the default ones.
    I installed the ATI Raid and SB (two seperate downloads on there web site and updated with every update 12.4 latest). My scores went from a 5.9 to 7.1 using SATA 3.0 WD drives 500MB.
