Nero CD Speed v4.01 - 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 DRU-810A performed very well when reading single layer DVD-ROM's. In the transfer rate tests, it started reading at 6.56x and reached a maximum transfer speed of 16.17x. While this wasn't enough to top the DRU-800A, the drive's seek times were also quite good.
Nero CD Speed v4.01 - 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.

Sony's new DVD writer had no problems reading Verbatim's 4x DVD-R DL media. The DRU-810A started reading at 5.01x and reached a maximum transfer speed of 12.07x.
Nero CD Speed v4.01 - 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 DRU-810A'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 DRU-810A either. With a maximum transfer speed of 12.09x, it had no problems taking the top spot in CD Speed's transfer rate tests.
Nero CD Speed v4.01 - 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 DRU-810A didn't slow down very much when reading single layer DVD videos. It started out at about 6.51x and reached a maximum read speed of 15.95x. Sony'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 the DRU-810A 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.
