MAX WEI score for a HDD is 5.9. I have recieved a 6.0 for a short stroked pair of HDDs in Raid0.
The only way to break the 5.9 barrier is using a SSD. For windows 7 they cap out at about 7.9
I knew that the SSD are some little cards that have huge speed + very expensive(in money)
I didn't know what was the biggest score for a HDD,thank you,this site is the best for my problems.
