Nero CD-DVD Speed: Basic DVD Tests

The second group of tests is concerned with DVD formats. I used six discs to get a fuller picture of performance of the drive: a DVD-ROM with a video movie and its copies made on DVD-R (Digitex), DVD-RW (TDK), DVD+R (Fujifilm), and DVD+RW (Verbatim) discs. Besides that, I used a dual-layer DVD+R from RIDATA.

The tested optical drive met no problems with the six DVD discs, but could not reach its specified 16x read speed on the DVD-ROM disc, however. Note also that the measured access time is noticeably smaller than specified by the manufacturer with all the tested discs.
