Nero CD Speed v4.7.7.16 - BD-ROM:
To test the PX-LB950UE's BD-ROM reading performance, I used the Blu-ray Disc version of The Fifth Element. This single layer disc is about 23GB in size.

The PX-LB950UE performed pretty well when reading BD-ROM discs. In our tests, the drive started reading at 3.37x and reached a maximum transfer speed of 8.08x.
Plextor's new Blu-ray Disc writer had no problems playing back The Fifth Element and The Simpsons Movie using the bundled version of PowerDVD. Just keep in mind that if your monitor is connected to your video card using DVI or HDMI, both need to be HDCP compliant to play AACS protected titles. If not, you can still play them by switching the connection to VGA or using software like Slysoft's AnyDVD HD.
Nero CD Speed v4.7.7.16 - BD-R and BD-RE:
Next we'll look at the drive's BD-R and BD-RE reading performance. For this I created a few data discs using single layer BD-R and BD-RE media from Memorex and TDK and then ran our BD read tests with CD Speed.
