The BH12LS38 was fairly quick when reading single layer DVD-ROM's. In our tests it started reading at 6.83x 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.

The BH12LS38 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 4.97x and quickly accelerates, reaching 12x at the 2.9GB mark. 

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 BH12LS38's performance was very similar to what we saw with DVD-R, DVD-RW and DVD-R DL media. The drive read DVD+R discs at 16x and both DVD+RW and DVD+R DL media at 12x.

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 BH12LS38 didn't do nearly as well as the other drives when reading DVD videos. In our tests, it reached a maximum speed of 12x when reading single layer discs. 

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 BH12LS38 had no problems playing back either movie and was fairly quiet.
