Nero CD Speed v4.10 - 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 SOHW-1673SU performed pretty well when reading single layer DVD-ROM's. In our tests it started reading at 6.66x and reached a maximum transfer speed of 16.24x. Looking at the other scores, you can see that the drive also had some good seek times.

Nero CD Speed v4.10 - 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 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. The results are below.

Lite-On's new drive wasn't nearly as fast when reading DVD-R and DVD-RW media. In both cases, the SOHW-1673SU reached a maximum transfer speed of about 8.1x.

While not officially supported, the SOHW-1673SU had no problems reading Verbatim's new dual layer DVD-R media. In our tests, the drive started reading at 2.39x and reached a maximum transfer speed of 5.72x.

Nero CD Speed v4.10 - 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.

While the SOHW-1673SU had no problems reading Verbatim's DVD+R DL media, it was not as fast as some of the other drives we've looked at. In our tests, it started reading at 2.39x and reached a maximum transfer speed of only 5.73x.

Nero CD Speed v4.10 - 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.

When reading single layer DVD videos, the SOHW-1673SU reached a maximum transfer speed of 16.08x. While not as fast as the drive from Plextor, this is still quite good. 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 8.24x.

To see how well the SOHW-1673SU worked as a DVD player, I watched a few scenes from Transformers: The Movie and Star Wars: The Phantom Menace using WinDVD 4 and PowerDVD 5. The drive had no problems playing back these movies with either program and was fairly quiet.
