Nero CD Speed: Data	Source: Ahead Software

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 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.

The AOpen CRW5232/ARR 52x32x52x CD-RW scores very well in Nero's CD speed when it comes to reading data CD's. Unlike in Sandra, Nero CD Speed seems to think that the AOpen drive has the fastest access time.

When it comes to audio, things are a bit different. The AOpen CRW5232/ARR 52x32x52x CD-RW is among the slowest of all the drives in average speed and seek times.
