Ssd problem (Samsung 830 series 64gb)

hi all about a month ago I built my first pc with an i5 2500k which I oc'd to 4.8 a 580 @ 960 MHz 8 gb vengeance ram p8z68 mobo western dig. 500 gb hdd and the Samsung ssd.

for the first time I actually looked at my windows score and CPU had 7.6 the rest had 7.9 but primary hard drive had a 5.6. now I really am not
concerned with the score itself, just after seeing the low hard drive score I got worried that something is wrong with the ssd.
