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 BenQ DW1625 did reach 40x without any problems. To see how this compares to other drives, look below:

Not the fastest drive due to the low reading speed of only 40x. But the seek times are pretty good.
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, but let us compare the result to some other drives:

Still not beating the drives that supports 48x reading of course, but the seek times is pretty good.
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 full 40x speed. Check how this compares to other drives below.

Pretty good, since most other drives limits the CD-RW reading speed to 32x.
Audio - Digital Audio Extraction:
To test the digital audio extraction performance of the BenQ DW1625, 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; let us compare the result with other drives:

Again, this is slower than some of the fastest, due to the reading speed of only 40x.
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 doesn't support reading data from the lead-out. This could affect the ability to extract audio from certain protected audio discs.
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 has no riplock and does nearly reach 16x with the single layer disc. The double layer disc is only read at 8x.

Pretty good, but we would like to see 12x reading speed 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 DVD+R/RW.

Slow due to the reading speed of only 8x, we would like to see 12x or 16x reading speeds for the DVD+R disc 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.
