For our CD transfer rate tests, we used the Nero CD-Speed utility and a set of Pressed CDs. The drive can read CD media at a maximum speed of 40X. For reference, we present a comparison of the Pioneer DVDRW drive with the LiteOn LH-20A1P, Memorex 525GE and Samsung SH S182D drives.
Pressed CD


US RW CD
The following CD Speed graph shows the reading performance with US-RW media. For all the CDSpeed graphs, you can click on the image to see the full CDspeed snapshot.


- AudioCD
In the CD Speed Advanced DAE quality test, the drive's average speed was 26.67X with a quality score of 100.


A typical DAE task with an 80min non-protected Audio CD produced 29.4X average ripping speed.

- 90/99 mins Audio disc


Both the 90min and the 99 min audio CDs produced an error, as you can see in the screenshots above.
- DVD Format
Now let's have a look at how the drive performs with DVD media. This time, a set of SL and DL DVD media was used. The drive is capable of reading at 16X maximum speed for single layer DVD ROM and at 12X for dual layer DVD ROM media.
DVD-ROM SL media -



PTP DVD-ROM -
The two layers of a PTP DVD-ROM disc are read sequentially with the drive starting reading from the inner part of the disc, which is the beginning of each layer, progressing towards its outer range.



The Pioneer drive is the fastest in this task.
OTP DVD-ROM -
The first layer of an OTP dual layer DVD-ROM
is read exactly the same way as the first layer of the PTP disc we tested previously.
The difference here is the reading strategy of the second layer of the disc.
The beginning of the second layer is located in the outer part of the disc,
so the drive starts reading from the outer tracks and progresses towards the inner part of
the disc.



Again, the DVR-112 is fastest.
