Nero CD-DVD Speed: Basic Tests (CD)

I use five CD media to perform these tests: a molded CD-ROM enclosed with a magazine, 700MB data CD-R and CD-RW discs recorded by Nero CD-DVD Speed itself, a likewise prepared 800MB CD-R, and an Audio CD.

The drive refused to read not only the 800MB CD-R, which is not a rare thing in my tests, but also the standard-size CD-R. This brings the new version of Nero CD-DVD Speed (4.60) under suspicion as I’ve never encountered this problem before. The diagrams don’t give me any reason to criticize the drive.

Here, we can see that the real speed limit for CD-RW and CD-DA media is about 40x instead of 48x. The measured access time is somewhat higher than the specified 100 milliseconds (for CDs). But the specification probably refers to CD-ROM whereas the access time is usually a little higher with other media types.
