Let’s now see if it’s different at 8x burn speed.

DVD+R Discs Burn Quality at 8x speed

MSI DR16-B2
 

BenQ DW1620
 

Both devices perform well in this test – their very low PIE/PIF rate is indicative of the highest quality of the resulting discs. But if the drives are compared with each other, the BenQ DW1620 looks better as it has about 5 and 3 times less PI Errors and Failures, respectively, than the MSI DR16-B2. So while the quality of the disc recorded by the MSI drive is just excellent, the quality of the disc from the BenQ is near etalon.

Beta/Jitter and TA Test for the DVD+R disc
burnt by the MSI DW16-B2 at 8x speed

The Beta graph is almost the same as at 4x burn speed. Beta is fluctuating just a little stronger, and the laser power is increased at the end of the disc. The Jitter rate has become more uniform throughout the disc than at 4x speed.

The improvements I have singled out are confirmed by the TA Test results. Jitter is minimal. The Peak Shift is still rather big, though. In other words, the average length of the pits and lands is not exactly as it should be. Yet the overall quality of the disc is very high.
