Nero CD Speed v4.7.7.16 - 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 DVD 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 DH-41BS performed fairly well when reading single layer DVD-ROM's. In our tests it started reading at 5.12x and reached a maximum transfer speed of 12.49x.Looking at the other scores, you can see that the drive's seek times were also quite good.
Nero CD Speed v4.7.7.16 - DVD-R and DVD-RW:
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 disk using some general use 16x DVD-R and 4x DVD-RW media from Verbatim and then ran our usual DVD read tests with CD Speed. The results are below.

Lite-On's new drive had no problems reading Verbatim's 4x DVD-R DL media. The DH-41BS started reading at 3.35x and reached a maximum transfer speed of 8.05x.
Nero CD Speed v4.7.7.16 - 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 disk 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 DH-41BS's performance with DVD+R and DVD+RW media was very similar to what we saw with DVD-R and DVD-RW media.Once again, the drive reached a maximum transfer speed of about 12.5x.

Reading Verbatim's double layer DVD+R media wasn't an issue for Lite-On's new drive either. The DH-41BS started reading at 3.35x and reached a maximum transfer speed of 8.05x.
Nero CD Speed v4.7.7.16 - 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 DH-41BS didn't slow down very much when reading single layer DVD videos. It started out at about 5.05x and reached a maximum read speed of 12.35x. Lite-On'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 8x.
To see how well Lite-On's new drive worked as a DVD player, I watched a few scenes from Transformers: The Movie and Star Wars: The Phantom Menace using the bundled version of PowerDVD. The DH-41BS had no problems playing back either movie and was fairly quiet.
