So far I have burnt 3 discs of the same thing, just a data disc with about 4.1GB on it, the first 2 were from the same tub one burnt at 8x and one burnt at 16x, the results were more or less the same, the 3rd disc was burnt at 8x from a different tub and again the same results.
All 3 discs read back perfectly fine with a nice smoove curve and no-drop offs, as you see below from the 16x burn. Although sometimes you get a faulty batch of discs, i reckon its mainly due to the reading drive. Unfortunaetly I dont have another drive available to me to to a comparison of a KProbe scan, guess I will have to buy one after the next payday.
Though the next questions being, get the BenQ drive or Lite-On drive?
