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.

NEC's new drive wasn't as fast as some of the others when reading single layer DVD-ROM's. While it came very close, the ND-4550A once again had a hard time reaching its rated speed in our tests. Unfortunately, its seek times were also a little higher than we'd like to see.
Nero CD Speed v4.10 - DVD-R, DVD-RW and DVD-RAM:
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. For the DVD-RAM tests, media from Maxell was used. The results are below.

When it comes to reading DVD-R and DVD-RW media, the ND-4550A is hard to beat. In our tests, the drive read DVD-RW discs at 13x and DVD-R media at an impressive 16x.

The ND-4550A wasn't as fast when reading Verbatim's 4x DVD-R DL media. As you can see, the drive started reading at 3.04x and reached a maximum transfer speed of only 7.29x. On top of that, its seek times were very high.

NEC's new drive has a maximum transfer speed of 5x when reading DVD-RAM discs. By looking at the screenshot, you can see that it reads at this speed from start to finish. While this gave the ND-4550A the advantage in the transfer rate tests, its seek times were again quite high.

The ND-4550A'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 13x.

Reading Verbatim's double layer DVD+R media wasn't a problem for the ND-4550A either. Unfortunately, with a maximum transfer speed of only 7.30x, it was the slowest out of the four drives here.

For these tests I am using the US version of Transformers: The Movie on DVD. The disc is over 4GB and single sided.

The ND-4550A performed surprisingly well when reading single layer DVD videos. It started out at about 6.49x and reached a maximum read speed of 15.82x. NEC'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 11.89x.
To see how well the ND-4550A 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.
