Performance in Nero CD-DVD Speed: Advanced DAE Quality Test
Exact Audio Copy and Nero CD DAE cannot “see” external optical drives, so I didn’t use these utilities in the current test session.
The Advanced DAE Quality Test helps determine hardware characteristics of an optical drive pertaining to the process of getting accurate copies of CD-DA media. Two CD-R discs prepared in Nero CD-DVD Speed are used in this test. One audio disc is normal; the other has defects of the surface, imitating your trying to make a copy from a long-used, bad-quality audio compact-disc.
The first screenshot is about processing the good audio CD. The average audio extraction speed is quite high; the resulting quality score is 100%. So, it seems the drive did its job well, but take note that it couldn’t read the lead-in and lead-out areas. The read offset is rather big, too, and differs from what was shown by PlexTools Professional which reported 408 bytes rather than 432.
The second screenshots shows the results with the bad audio CD. The drive did well here. The average track extraction speed is but a little lower than with the good CD. The number of errors is low, so it is no wonder the drive turns in a 100% quality score again.
