Performance in Nero CD-DVD Speed: Basic CD Tests
I use five CD media to perform these tests: a molded CD-ROM enclosed with a computer 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. Unfortunately, the drive could not read the 800MB CD-R to the end, producing an error message.
The drive processes CD media well, except for the above-mentioned 800MB CD-R. It produces similar results and reaches a read speed of 40x with all the media types, including CD-RW (optical drives usually perform slower with CD-RW media).
Note that the measured access time is smaller than the specified value irrespective of the disc type.
