DVD+R Discs Burn Quality at 12x speed
Once again I can’t but praise the results of both models. But if we compare them with each other, the BenQ DW1620 will seem noticeably better than the MSI, its average PI Error rate being about 3 against the MSI’s 8. The total number of PI Error blocks differs by a factor of five (you can easily guess which drive has more of them). The difference in the number of PI Failure blocks is not as big as at 8x burn speed, though. It is only 9 blocks. So, we again get one excellent and one very good result.
Beta/Jitter and TA Test for the DVD+R disc
The Beta parameter fluctuates stronger here than at 8x burn speed, yet it always remains within the actable range. You can see that the MSI DR16-B2 still reduces the laser power of its write head at the last quarter of the blank. The Jitter rate remains on roughly the same level throughout the disc, even though with some deviations. The TA Test results prove that the Jitter rate is higher for this disc than for the 8x DVD+R, but not much high, and only for the small-length pits and lands. The Peak Shift is the same as at 8x speed.
