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 supports:
- DVD-ROM : 16x
- CD-ROM : 40x
Pressed CD-ROM disc:
For this test we used a pressed CD-ROM disc containing Nero Express OEM install CD that is close to 77 minutes long. Below you will see the produced result:

The Matshita DVD-RAM SW-9585 reached 42.18x. Let's see how this compares to some other drives below:

The Matshita DVD-RAM SW-9585 appears to be one of the faster 40x readers but the seek times are incredibly high.
CD-Recordable Discs:
For this test we used a Data CD-R that was made using Nero CD-DVD Speeds 'create data disc". The disc we used is a Sony 48X certified CD-R manufactured by Sony Corporation.

From the table above we see again that the Matshita DVD-RAM SW-9585 was one of the faster readers on CD-R in comparison to other drives but shows those high seek times again.
CD-Rewritable discs:
Again, we made a Data CD with Nero CD-DVD Speeds 'create data disc". This time we used a Maxell High Speed (12X) CD-RW disc made by Mitsubishi.

As we can see above, the Matshita DVD-RAM SW-9585 only reads CD-RW discs at 25.30x. Let's compare it to other drives below.

The Matshita DVD-RAM SW-9585 scored last among the compared drives reading CD-RWs. The access times are very high again.
Audio - Digital Audio Extraction:
To test the digital audio extraction performance of the Matshita DVD-RAM SW-9585, we again used Nero CD/DVD-Speed to measure the transfer rate. The audio disc we used is shorter than the disc used for the other tests, measuring in at 74 minutes long (74:00:00).

The drive reached 24.39x reading the audio disc back. Let's compare the result with other drives:

The Matshita DVD-RAM SW-9585 performed extremely slow reading Audio-discs reaching only 24.93x. The access times are extremely high.
And as a last test we used Exact Audio Copy (EAC) to extract the audio to our hard drive. According to EAC the drive does not support caching, which is considered a plus - while ripping audio.

Below is the results produced by EAC:

Burst mode

Secure mode
The drives performance in EAC is quite slow.
Advanced audio - DAE quality test:
Before we move on to testing DVD read speeds, we will take a last audio test, and this time we used the 'Advanced DAE Quality Test" feature in CD-DVD Speed.

The extracting quality is excellent. It supports all Advanced Features except reading from the Leadout. Using the MATSHITA DVD-RAM SW-9585 as a reader for On the Fly Copying above 10x is reported as 'too slow".
DVD reading performance:
Again, we will use Nero CD-DVD 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 a 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.


DVD-Video Single Layer

DVD-Video Double Layer
As we could see the drive read single layer DVD-Video at 16X CAV and double layer DVD-Video at 4x. To see how the transfer rate is on a Data DVD we used the PS/2 game ATV Off Road Fury 2 DVD-ROM:


As we could see the Matshita DVD-RAM SW-9585 had no problem reading the DVD-ROM back at CAV 16x.

DVD - DVD+R(W):
For this test we used a FujiFilm 8X DVD+R and a Memorex 4X DVD+RW with 4.38Gb of data. Below are the results:

DVD+R

DVD+RW
The reading speed was locked to 8x for DVD+RW, which is fairly normal for most new drives.
