Now let’s check the quality of the discs the drives wrote at their maximum speed.
Burned CD-R read graphs at 52x speed (Nero Quality Check)
Nero Quality Check report
When the write speed is the highest, the AOpen COM5232/AAH again produces a disc of the best quality – the total of C2 errors is 103, in one surge. The Samsung TS-H492A has the same number of errors of the second encoder, and in a single surge, too. The Samsung SM-352N has nothing to be proud of – two surges with a total of 1568 errors, and a peak of 888 errors.
Now, about the first encoder: the AOpen is the best with 1465 errors; next goes the Samsung TS-H492A with 1531 errors. Overall, the AOpen COM5232/AAH and the new Samsung produce high-quality discs, both at the maximum and reduced burn speeds. The Samsung SM-352N is just a little worse than these two drives at 24x speed, but the difference becomes more evident at 52x speed.
As I mentioned above, the AOpen COM5232/AAH agreed to burn a Verbatim 48x blank at 52x speed. Why not to check it out?
Well, the result is worse than with the disc rated for 52x speed, but good enough for this non-standard operational mode: a single surge of the first encoder errors (106), which is only three errors more than in the regular work mode. The C1 error count grew more, from 1465 to 3731. Anyway, the AOpen handled this blank in a most appropriate way. For example, it made fewer errors than the Samsung SM-352N, which was writing a 52x blank at 52x speed. These are all preliminary results, though. I will voice my final verdict after looking through the results of CD CATS SA3. That’s what I’m going to do right now.
