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-1673S did reach 48x at the end. To see how this compares to other drives, look below:
| Pressed | Average | Start | End | Seek | Seek | Seek |

| Lite-On | 36.44x | 21.36x | 48.13x | 118ms | 133ms | 207ms |
The Lite-On SOHW-1673S performed pretty well and is among the faster drives.
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.
| CD-R | Average | Start | End | Seek | Seek | Seek |
| BenQ | 30.76x | 17.60x | 40.41x | 96ms | 106ms | 157ms |
| Pioneer | 31.13x | 18.21x | 41.08x | 125ms | 143ms | 282ms |
| Samsung | 36.49x | 21.20x | 48.13x | 91ms | 96ms | 165ms |
| Mad Dog | 35.49x | 20.74x | 46.78x | 125ms | 131ms | 189ms |
| Philips | 36.54x | 21.46x | 48.14x | 124ms | 151ms | 230ms |
| Memorex | 36.39x | 21.63x | 47.96x | 127ms | 155ms | 231ms |
| AOpen | 36.49x | 21.20x | 48.11x | 99ms | 115ms | 185ms |
| LG | 30.63x | 17.62x | 40.14x | 105ms | 129ms | 183ms |
| Lite-On | 36.63x | 21.46x | 48.29x | 125ms | 157ms | 234ms |
| LG | 30.71x | 16.90x | 40.37x | 121ms | 110ms | 110ms |
| Lite-On | 36.53x | 21.42x | 48.20x | 124ms | 153ms | 231ms |
Again - pretty good, as expected.
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 speed. Check how this compares to other drives below.
| CD-RW | Average | Start | End | Seek | Seek | Seek |
| BenQ | 31.36x | 17.55x | 41.44x | 109ms | 113ms | 194ms |

Unfortunately it's among the slower drives due to the read speed limit of 32x speed.
Audio - Digital Audio Extraction:
To test the digital audio extraction performance of the Lite-On SOHW-1673S, 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 - among the faster drives.
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, and it supports all features. This is very good performance and a highly recommended drive for audio extraction.
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.
This drive does not have any riplock as it reads the single layer disc at full 16x speed, but we would like to see slightly higher reading speed than 8x for reading the double layer disc.

The Lite-On SOHW-1673S is pretty fast for the single layer disc, but we would like to see higher speeds than 8x for the double layer disc.
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 both DVD+R and DVD+RW.

Among the slower drives due to the low 8x reading speed. We would like to see higher reading speeds for 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.
