So I have an ssd san disk hard drive that runs as my main hard drive.I recently bought the nvidia geforce gtx 770 and put it in my computer. After I put in my new driver I went to run the computer performance assessment to see how much higher my gaming graphics improved. The graphics did improve from 7.6 to 7.9 but for some reason my ssd hard drive's score dropped down from 7.7 to 5.9. After this I started seeing slower performance with the start up and file transfers. I did some research and tried many ways to boost ssd speed but the score remains at 5.9.
