Nero CD Speed: Data	Source: Ahead Software

CD Speed is a CD/DVD-ROM benchmark which can test the most important features of a CD-ROM drive. In this particular test we use a pressed CD-ROM with about 640MB of data as the test disk. Using a CDR or CDRW as the test disk may (or may not) impact the results slightly, so the pressed disk is the de facto standard.

In Nero CD Speed, the average speed in reading data CD's is a tad on the low side but nothing to worry some. CPU usage also seems a bit on the high side, but disc recognition time is pretty good.

CD Speed is a CD-ROM benchmark which can test the most important features of a CD-ROM drive. In this particular test we use a pressed Audio CD with about 65 minutes of audio on it as the test disk. CDROM's in general have a harder time processing audio data, and hence the results can be drastically slower than that of data tests alone.
