Burning the CD-RW disc at 32x speed
The burn process proper hardly needs any comments, so let’s get right to the results of the quality check.
CD-RW disc burning quality at 32x speed
Neither drive is supposed to be able to burn discs of that type, so they both perform worse than with 24x CD-RWs. The BenQ, however, has better results than the MSI drive. It has 2.5 times less C1 errors and no C2 errors (780 C2 errors were found on the disc recorded by the MSI drive). I should note once again that the BenQ DW1620 only boasts such results with its B7T9 firmware. Before the release of this firmware version the drive produced absolutely unreadable 32x CD-RWs.
The Beta graphs have the same shape as with the 24x CD-RWs: a horizontal line lying at the zero mark for the disc from the MSI drive while the BenQ uses a higher laser power than the MSI. The Jitter rate is far from ideal on both discs, especially on the innermost tracks.
As you have seen in the CD-RW tests, BenQ was more successful than MSI in correcting the defects noticed in its drive. As a result, the BenQ DW1620 boasts a much higher CD-RW burn quality than its opponent, even though the results of the MSI DR16-B2 are good, especially at the officially supported burn speed.
