Reading performance:

We will use Nero CD/DVD-Speed to read various CD and DVD media.

Pressed CD-ROM discs:

We used an original pressed CD-ROM disc containing 72.39.55 minutes of data.

The LG GGW-H20L reaches the reading speed of 40.36X.

For comparison we have made the following table:

As you can see from our chart the LG GGW-H20L is one of the fastest drives reading pressed CD-ROM discs with respectable seek times.

CD-Recordable Discs:  

For this test we used a Maxell CD-R disc manufactured by Ritek; the disc was burned full with data using Nero CD-DVD Speed.

The LG GGW-H20L reached 39.56X when reading the copied CD-R disc.

For comparison we have made the following table:

The LG GGW-H20L is right there with the top performers when reading CD-Recordable discs, with some nice seek times.

CD-Rewritable discs: 

We made another Data CD with Nero Express “Copy Entire CD”, this time we are using a Verbatim DataLifePlus Ultra Speed+ (32X) CD-RW disc.

The LG GGW-H20L read the CD-RW discs back at 39.53X speed.

For comparison we have made the following table:

The LG GGW-H20L was the second fastest at reading our CD-Rewritable disc. 

Audio – Digital Audio Extraction

To test the digital audio extraction performance of the LG GGW-H20L we used Nero CD-DVD Speed to measure the transfer rate. The audio disc we used is 74 minutes in length.

The LG GGW-H20L reached 37.98X when reading our audio disc

For comparison we have made the following table:

The LG GGW-H20L performs nicely when reading the Audio-CD disc.

Advanced audio – DAE quality test:

For the Advanced Audio DAE test we used the “Advanced DAE Quality Test” feature of Nero CD-DVD Speed.  The CD-R media used is a 40X certified Memorex Music CD-R manufactured by Ritek. (Thanks to Memorex USA for sending us this media.)

The LG GGW-H20L will permit “On-The-Fly” copying at all tested speeds through 16X; the drive does not support reading data from the Lead-Out.

DVD reading performance:

DVD-ROM “Pressed Disc”

We utilized Nero CD-DVD Speed to measure the reading performance.  We will to the reading performance testing on various types of DVD discs.  To start off with we will test the LG GGW-H20L at reading “Pressed” DVD-Video discs both Single Layer and Double Layer.

DVD-Video Single Layer

DVD-Video Double Layer

The LG GGW-H20L reads both SL and DL pressed DVD-Video discs at 8X.

For comparison we have made the following table:

The LG GGW-H20L performs right there with the fastest drives on both DVD-Video Single Layer and DVD-Video Double Layer reading tests.

DVD+R/RW:

For testing the read speed of DVD+R and DVD+RW discs we used Verbatim 16X DVD+R and 8X DVD+RW.  Both Discs were written with 4.38GB of data using Nero CD-DVD Speed.  (Thanks to Verbatim USA for sending us this media.) See the results below:

DVD+R

DVD+RW

We have prepared this table to show you how the LG GGW-H20L reads DVD+R/RW media as compared with other drives:

The drive posts respectable speeds when reading our test discs.  Reading DVD+R disc at over 12.14X speed and the DVD+RW disc at 10.05X speed.

Now let’s see how it will perform on DVD-R/RW discs.

DVD-R/RW:  

For testing the DVD-R and DVD-RW reading performance we used Verbatim discs we used Verbatim 16X DVD-R and 6X DVD-RW.  (Thanks to Verbatim USA for sending us this media.) Below you will find our test results.

DVD-R

DVD-RW

We have also provided this table to show how the LG GGW-H20L compares with other drives for reading these media:

The drive performs on the top end; reading the DVD-R disc at over 12X speed and the DVD-RW disc at over 10X speed.

DVD±R DL:  

For this test we used a Verbatim DVD±R DL discs filled with data.

DVD+R DL

DVD-R DL

Below we have provided a table to show how the LG GGW-H20L compares with other Blu-ray drives.

The drive performs average while reading DVD+R DL and DVD-R DL at just over 8X speed.

DVD-RAM

For this part of our test we are using a Maxell 5x DVD-RAM filled with 4.27GB of data. Our test results are found below:

The LG GGW-H20L will read DVD-RAM at 5X; reading this disc in 12 minutes and 12 seconds.

Summary

The LG GGW-H20L is a fast reader while reading CD media, Single Layer DVD and it performs on average when compared with the rest of the pack when reading Dual Layer DVD media.

Now it’s time to head on to the next section: Writing Quality with CD-R and CD-RW discs…
