Burning the CD-R disc at 24x speed
These two graphs are shaped so identically that they might coincide if I were to put them one upon another. The burn processes are absolutely the same in both cases. This is also confirmed by the fact that the duration of the burn sessions was almost the same (with a 4-second discrepancy). But will the quality of the discs differ as in the previous test?
CD-R disc burning quality at 24x speed
I suspect the MSI DR16-B2 again suffers from some defects in its OPC algorithm – there is a small surge of C1 errors at the beginning of the disc, and some C2 errors appear, too. Otherwise, the quality of the disc from the MSI drive is higher than of the disc from the BenQ. For example, the average BLER for the BenQ disc is about 16, and for the MSI disc – less than 8. The total number of C1 errors is two times smaller on the MSI disc than on the competitor’s, too.
The Beta graphs are similar, but the BenQ again starts to burn the disc at a higher laser power. The Jitter rate is better on the BenQ disc and is simply terrible on the MSI disc – our reference optical drive even stopped to read the MSI disc in that test (I attempted to repeat the test a few times more, but with the same, negative, result). Strangely enough, the high Jitter rate on the disc recorded by the MSI DR16-B2 is not accompanied with an abundance of errors.
Next goes 16x burn speed.
