The UH10LS20 was fairly quick when reading single layer DVD-ROM's. In our tests it started reading at 6.81x and reached a maximum transfer speed of 16.48x. Looking at the other scores, you can see that the drive's access 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 6x 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.

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 16x DVD+R and 8x DVD+RW media from Verbatim. I then ran our usual DVD read tests with CD Speed. The results are below.

The UH10LS20 didn't do as well as some of the other drives when reading DVD videos. In our tests, it started out at about 5.05x and reached a maximum read speed of only 12.21x.
To see how well LG'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 UH10LS20 had no problems playing back either movie and was fairly quiet.
