Reading performance:
For these tests we will use Nero CD-DVD Speed to read various CD and DVD's, including audio discs and DVD-Video. According to the product box, this drive supports a specified read speed of 16X for DVD-ROM's and 40X for CD-ROM's.
Pressed CD-ROM
discs:
For this test we used a
pressed CD-ROM disc containing Canon Digital Camera Solution Disk ver 9.0 that
is 73:12.38 minutes long. Below you will see the produced result:

We can see that the drive reads pressed CD-ROM discs exactly as the specification suggests. 40X CAV (Constant Angular Velocity) reading. Let us compare this to some other drives;

Please note that the test disc size can vary slightly in these tests. The table should be used as a rough comparison between drives.
The ASUS DRW-1604P is one of the slowest readers. The drive is slower than the competition because other drives can support reading CD-ROM discs up to 48x.
CD-Recordable discs:
For this test we made a copy of the original Canon Digital Camera Solution CD. The disc we used was a Verbatim 48X certified CD-R disc manufactured by Mitsubishi Chemicals Corporation.

The results look almost identical to the CD-ROM reading graph. The drive has no trouble hitting 40x on CD-Recordable discs.

Please note that the test disc size can vary slightly in these tests. The table should be used as a rough comparison between drives.
Again we can see the drive is slower than some of the competing drives due to its 40x CD-R read limitation.
CD-ReWriteable discs:
The disc we used was a Verbatim HighSpeed 12X CD-RW disc manufactured by Mitsubishi Chemicals Corporation.

The drive reads CD-RW at a speed of 32x CAV (Constant Angular Velocity).

Please note that the test disc size can vary slightly in these tests. The table should be used as a rough comparison between drives.
The drive is about average with CD-RW reading speed, but we would still rather see 40x or 48x CD-RW reading.
Audio - Digital Audio Extraction:
To test the digital audio extraction performance of the ASUS DRW-1604P, we again used Nero CD/DVD-Speed to measure the transfer rate. The audio disc we used is approximately 74 minutes long (74:02:70).

Here we can see that the CD-Audio reading speed is also 40x CAV with perfect DAE quality. Let's do another comparison!

Please note that the test disc size can vary slightly in these tests. The table should be used as a rough comparison between drives.
The drive performs about average here as well.
Advanced Audio - DAE quality test:
Before we move on to testing DVD read speeds, we perform one last audio test. This time we used the 'Advanced DAE Quality Test" feature in CD-Speed.

The drive performed as expected in these tests. The drive was able to read CD Text and Subchannel Data, which is a positive. Unfortunately it does not support reading from the Leadin or Leadout.
DVD Reading performance:
Again we will use Nero CD-DVD Speed to measure the reading performance, this time for various types of DVD discs. According to the specifications, the drive should read pressed single layer DVD-ROM 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 is 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.

Single
Layer DVD Video

Double
Layer DVD Video.
We can see that the drive is locked to 5x CAV (Constant Angular Velocity) for both Single Layer and Double Layer DVD Video discs. This 5x 'riplock' is not desirable and will annoy users who wish to rip their DVD Video discs at full speed. How does this compare to other drives? Check the table below to find out!
