Nero CD Speed v4.70 - 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-755UF performed pretty well when reading single layer DVD-ROM's. In our tests it started reading at 6.63x and reached a maximum transfer speed of about 16.12x.
Nero CD Speed v4.70 - 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.

Plextor's new drive wasn't nearly as fast when reading DVD-R and DVD-RW media. In both cases, the PX-755UF reached a maximum transfer speed of about 12.1x.

The PX-755UF had no problems reading Verbatim's 4x DVD-R DL media. In our tests it started reading at 3.35x and reached a maximum transfer speed of 8.06x.
Nero CD Speed v4.70 - 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-755UF's performance with DVD+R and DVD+RW media was very similar to what we saw with DVD-R and DVD-RW media. Here too the drive reached a maximum read speed of about 12.1x.

Reading Verbatim's double layer DVD+R media wasn't a problem for the PX-755UF either. While not nearly as fast as the drive from LG, it reached a maximum transfer speed of 8.07x.
Nero CD Speed v4.70 - 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-755UF has two different modes when reading DVD videos. To reduce noise, the drive reads these discs at 2x by default. While this isn't very fast, you can increase the drive's maximum transfer speed by enabling SpeedRead. With SpeedRead enabled, the PX-760A was able to read single layer DVD videos at 16x and dual layer discs at 12x.
To see how well the PX-755UF 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 very quiet when SpeedRead was disabled.
