Reading performance

For these tests we will use Nero CD-Speed to read various CD and DVD’s, including audio discs and DVD-media. As already mentioned in the introduction, this drive supports:

  • DVD-ROM 16x
  • CD-ROM 48x

Pressed discs:

For this test we used a pressed CD-ROM disc containing the Roxio Media Creator 9 install CD that is close to 73 minutes in length. Below you will see the produced result:

The LG GH22LP20 was about average drives when reading our test CD-ROM media.

If this reviewer had a Pressed CD that contains data closer to the desired 75 minute mark this drive would surely have reached its highest rated read speed.

Seek times were very good.

CD Recordable discs:

For this test we made a data disc with CD-DVD Speed. The disc we used was a Maxell CD-R certified for 48X writing.

On-the-fly coping up to and including 12X is supported, read lead out was not supported.


DVD reading performance:

Again, we will use Nero CD-Speed 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 a single and Double Layered 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.
