The Plextor PX-B310U was one fastest drive when reading our test CD-RW.
Audio – Digital Audio Extraction:
To test the digital audio extraction performance of the Plextor PX-B310U, again we used Nero CD/DVD-Speed to measure the transfer rate. The audio disc we used is slightly larger than the disc used for the other tests, to be exact it’s nearly 79 minutes in length (78:56:45).
The Plextor PX-B310U reached 18.05x when reading our test audio disc. Let’s compare it with some drives below.

The Plextor PX-B310U was gave a poor results when reading our test CD-Audio disc.
DVD reading performance:
Again, we will use Nero CD-Speed and Opti Drive Control to measure the reading performance, this time for various types of DVD discs. The drive should read pressed single layer DVD-discs at 16X.
Pressed DVD Video:
For our DVD reading performance tests we are going to start with single and Double Layer DVD video discs. While only 1X speed is required to watch DVD movies, it’s useful to be able to read the discs at higher speeds if you’re going to extract (rip) the content of the disc to your hard drive.
DVD Video (Single Layer)
DVD Video (double layer OTP)
The Plextor PX-B310U is not riplocked and is able to read our single layer disc at 16x and our double layer test discs at 12x
We present the table below for comparison with other Blu-ray drives.

The Plextor PX-B310U was the slowest drive we have tested when reading our test DVD±DL media.
Blu-ray reading performance:
BD-ROM SL
We selected a BD-ROM SL disc containing a movie, Underworld.
The Plextor PX-B310U read our BD-ROM DL media at 6x reading speed.
BD-ROM DL:
We selected a BD-ROM DL disc containing the movie, Quantum of solace.
The Plextor PX-B310U read our DL BD-ROM media at 4x reading speed.
BD-R:
The Plextor PX-B310U read our BD-R disc at 6x reading speed.
BD-RE:
The Plextor PX-B310U read our BD-RE at 6x reading speed.
Summary:
The Plextor PX-B310U is a fast reader of BD media, it could reach 6x on single layer media BD-ROM/-R/-RE and 4x on Dual Layer BD media, and all this from the USB port.
Now let’s head over to the next page where we will test CD-R/RW writing performance……
