Nero CD Speed v4.7.5 - DVD-ROM:
A little editorial note here. Like a CD-ROM, you will get different benchmark results depending on what kind of discs you are using. You are probably going to get varying results from a full data disc to a single layer movie disc. You're also going to get different results for single and dual layer discs.
The CD Speed website recommends using a single layer DVD-ROM disc with a capacity of at least 4GB. If you use a dual layer disc you probably won't get the best results because most DVD-ROM drives slow down to read them. Some even slow down to read single layer DVD-Video discs. To make a long story short, I am using a 4.37GB single layer, single sided disc for this test.

The SH-S203B performed very well when reading single layer DVD-ROM's. In our tests it started reading at 6.72x and reached a maximum transfer speed of 16.21x.Looking at the other scores, you can see that the drive's seek times and CPU usage were also quite good.
Nero CD Speed v4.7.5 - DVD-R, DVD-RW and DVD-RAM:
First, we'll look at the drive's DVD-R and DVD-RW reading performance. For this I made copies of our DVD-ROM test disc using some general use 4x DVD-R and 2x DVD-RW media from Verbatim and then ran our usual DVD read tests with CD Speed. For the DVD-RAM tests, media from Maxell was used. The results are below.

Samsung's new drive has a maximum transfer speed of 12x when reading DVD-RAM discs. By looking at the screenshot you can see that it starts reading at 5.91x and accelerates, reaching 12x at the 2.7GB mark.
Nero CD Speed v4.7.5 - DVD+R and DVD+RW:
Next we'll look at the drive's DVD+R and DVD+RW reading performance. For this I made a copy of our DVD-ROM test disc using some 4x DVD+R and 2.4x DVD+RW media from Verbatim. I then ran our usual DVD read tests with CD Speed. The results are below.

The SH-S203B's performance with DVD+R and DVD+RW media was very similar to what we saw with DVD-R and DVD-RW media.The drive read DVD+R discs at 16x and DVD+RW media at 12x.

Reading Verbatim's double layer DVD+R media wasn't an issue for the SH-S203B either. The drive started reading at 5.12x and reached a maximum transfer speed of 12.30x.
Nero CD Speed v4.7.5 - DVD-Video:
For these tests I am using the US version of Transformers: The Movie on DVD. The disc is over 4GB and single sided.

The SH-S203B didn't slow down very much when reading single layer DVD videos. It started out at about 6.65x and reached a maximum read speed of 16.05x. Samsung's new drive was also fairly quick when reading dual layer discs. By looking at the screenshot below, you can see that the drive's transfer speeds peaked at about 12x.
To see how well the SH-S203B worked as a DVD player, I watched a few scenes from Transformers: The Movie and Star Wars: The Phantom Menace using Nero Showtime. The drive had no problems playing back these movies with either program and was fairly quiet.
