I have never used this program until today. i ran it on my C drive, intel X25 2nd gen. im not sure how our drives are meant to stack up, i got mine about a year and 6 months ago now.
go into your power settings and make sure all power management and saving features are off inside of windows. that can cause performance issues. aside from that 5mb is not a huge issue, thats well with in the margin of error for such tests.
