Performance in Nero CD-DVD Speed: Basic DVD Tests

The second group of tests is about DVD formats. I took seven 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. I also used a dual-layer DVD+R from RIDATA and a 3x Verbatim DVD-RAM.

• DVD-R (Graph)
• DVD-RW (Graph)
• DVD+R (Graph)
• DVD+RW (Graph)
• DVD+R DL (Graph)
• DVD-RAM (Graph)

The data-transfer diagrams betray no problems. The maximum speed was quite expectably achieved with the DVD-ROM. The drive had the lowest speed when processing the DVD-RAM – the transfer graph shows the DVD-RAM was being read at a constant linear speed.

Note that the measured access time is higher than declared with the DVD+R DL and DVD-RAM discs.
