The rating is not dependant on your OS edition. It is a benchmark of your HDDs performance. You may have bought one with less cache, or slower spin or it may just be outright worse.

If you are confident you've bought a better HDD than your original then I'd look at whether it is running in IDE or AHCI mode in the BIOS. If you discover it is running in IDE mode then report back for instructions - DO NOT just change it, windows will not boot without the appropriate driver.

Also, as above, post up your old and new HDD details.
