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 PX-750A wasn't as fast as some of the others when reading single layer DVD-ROM's. While it came close, Plextor's new drive again had a hard time reaching its rated speed in our tests.
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.

The PX-750A had no problems reading DVD-R, DVD-RW and DVD-R DL media. In our tests, it was able to read DVD-R discs at speeds near 10x, but slowed to about 8x when reading DVD-RW and DVD-R DL media.

Plextor'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.
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.

The PX-750A'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 10x and DVD+RW media at 8x.

Reading Verbatim's double layer DVD+R media wasn't a problem for the PX-750A either. While not as fast as the drive from LG, it reached a respectable 7.99x in CD Speed's transfer rate tests.
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.

The PX-750A didn't slow down very much when reading single layer DVD videos. It started out at about 6.48x and reached a maximum read speed of 15.75x. Plextor'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 7.96x.
To see how well the PX-750A 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.
