If you look at the uncached write under random, you will see a 4.43. That is consistent!

I have almost got everything on this Gateway 450ROG laptop working (sound, video (no QE/CI), wireless, DVD burner) but a few things still are not right. A 4.43 is pretty freakin low! (would also love working QE/CI (opengl) with this ati 7500)

Any ideas guys? I KNOW this laptop drive is not that slow, its a 7200rpm!

Uncached write, especially random, is a very time consuming process. To get a score of 100 (I believe) you would need a HD that spun at 15000RPM with a seek time of about a milisecond. Until technology gets that far, a 4 is decent. By the way, Xbench isn't all that reliable ;)
