Reading performance:
For these tests we will use Nero CD/DVD-Speed to read various CD and DVD's, including audio discs and DVD-media. As already mentioned in the introduction, this drive sports a specified read speed of 16X for DVD's and 40X for CD's.
Pressed discs:
For this test we used a pressed CD-ROM disc containing PlexTools v1.08 that is exactly 74 minutes long. Below you will see the produced result:
The LG GSA-5163D did reach 40x at the end. To see how this compares to other drives, look below:

AS we could see it lags behind many of the other drives due to the lower reading speed of only 40x compared to 48x for many of the other new drives. But the seek times are among the best we have ever seen.
CD-Recordable Discs:
For this test we made a copy of the original PlexTools v1.08 CD. The disc we used was a Verbatim 48X certified CD-R disc manufactured by Mitsubishi Chemicals Corporation.
No big differences compared to reading the original pressed disc.

Again slower than the other drives, but the seek times is among the better we have seen.
CD-ReWritable discs:
Again we made a copy of the original PlexTools v1.08 disc, this time we used a Verbatim High Speed (10X) CD-RW disc made by Mitsubishi Chemicals Corporation.
The drive reads CD-RW discs faster than pressed discs and CD-R discs! Check how this compares to other drives below.

Among the faster drives for reading CD-RW discs, due to many drives reading CD-RW discs at 32x only. Again good seek times.
Audio - Digital Audio Extraction:
To test the digital audio extraction performance of the LG GSA-5163D, we again 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 about 78 minutes long (77:56:57).
The drive had no problems with reading the audio disc at full speed and everything seems good, so let us compare the result with other drives:

Good seek times again, but lagging behind other drives speed wise as it reads at 40x only.
Advanced audio - DAE quality test:
Before we move on to testing DVD read speeds, we will take a last audio test. This time we used the 'Advanced DAE Quality Test" feature in CD-Speed.
The extracting quality should be excellent, but it does not support reading data from the lead out nor from the subchannel.
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.
DVD - DVD-Video:
For our DVD reading performance tests we are going to start with single and dual 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.
As we can see, this drive reads both single layer and double layer DVD-Video discs at 8x speed. That means that the drive is locked at 8x for reading DVD-Video discs.

The LG GSA-5163D is among the slower readers for reading DVD-Video discs, this is due to speed lock at 8x.
DVD+R(W):
For this test we used a Taiyo Yuden 4X DVD+R and a Ricoh 4X DVD+RW with about 4,4Gb of data. Below are the results:
The reading speed was locked to 10x for DVD+R and 8x for DVD+RW.

About average compared to other drives, but we would like to see 16x reading of DVD+R media at least.
DVD - DVD-R/RW:
For this test we used a Taiyo Yuden 4X DVD-R disc and a Verbatim 2X DVD-RW disc filled with about 4,4Gb of data. Our test results are found below:
There are hardly any differences compared to reading the DVD+R/RW discs.
