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 48X 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 Lite-On SOHW-1653S reached 48x at the end, to see how this compares to other drives, look below:

The speed is very good - among the fastest we have seen so far. But the seek times could be improved.
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.
Again a good result, look below for a comparison table.

Same here as well, good speed but poor seek times.
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 at only 32x. Check how this compares to other drives below.

Lags behind the best drives due to a reading speed of only 32x, and the seek times are still a lot higher than for the other drives.
Audio - Digital Audio Extraction:
To test the digital audio extraction performance of the Lite-On SOHW-1653S, 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:

Again - good speed, but poor seek times.
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.
It simply impressed in this test, everything is as good as it could possibly be! Excellent speed and quality as well as supporting all features.
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 single layer DVD-Video discs at almost 16x speed and double layer DVD-Video discs at 8x speed, pretty average - but we would like to see at least 12x reading speed for double layer discs. How this compares to other drives may be seen in the table below.

The Lite-On SOHW-1653S is far from the fastest writer, but it is at least not locked to low speeds for reading DVD-Video discs.
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 8x for DVD+R and DVD+RW.

The Lite-On SOHW-1653S with its reading speed of only 8x is among the slowest readers for DVD+R/RW media.
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.
