Nero CD Speed: Advanced DAE Quality

This test checks how well the sound tracks can be extracted from a pre-recorded disk with 100% certainty. The “on-the-fly” copying is not too fast, though, it occurs at 4x only. The drive couldn’t read the data from Leadin and Subchannel. The positioning precision of the drive is not very high. Thus, it suits well for work with audio CDs, but you can’t hope for any super-precise results.

Nero CD Speed: Quality Check

What can you expect from a drive if the disk surface is damaged? Quality Check test will help to answer this question. Here we used a specially prepared CD with the damaged surface. You see the illustrative results in the screenshot. You realize that no positive outcome is possible in case of scratched disks or any other surface artifacts. More than three million errors are a way too much to give you even the tiniest hope for success when reading disks like that.

CD-RW

This is a simple program developed by one our Russian colleague, which we used to recheck the results of Nero CD Speed. The read speeds on a printed CD, CD-R and CD-RW were close to what we saw above. The drive shows the claimed speed on the CD-ROM and CD-R and slows down in case of CD-RW.
