| Description | Introducing Smart-Write™ - Self-learning technology ensuring best writing quality with all media. |
Writing Data CD-R/RW discs:
The specifications state that the drive should be able to write CD-Rs at 48x and CD-RWs at 32x.
CD-R:
The Lite-On LH-18A1P uses CAV (Constant Angular Velocity) to write CD-R’s at 48x. This gives an average writing speed of 37.12x and a writing time of 2 minutes and 39 seconds.
CD-RW:
The Lite-On LH-18A1P uses Z-CLV, (Zone-Constant Linear Velocity) to write CD-RWs at 32x. The average speed is 24.99x and total writing time is 3 minutes and 59 seconds.
In this preview, we did not include any quality scans of the CD-R/RW discs.
DVD-Writing performance:
The specifications of this drive tell us that it should write DVD±R at 18x, DVD+RW/-RW at 8x/6x, and DVD±R DL at 8x. In these tests we will be using a Lite-On SHW-165P6S with firmware MS0P along with KProbe to measure the disc quality. We will also be using the Optiarc AD-7173A with firmware 1-01 along with CD-Speed for our read-back tests.
EDITORS NOTE: Some DVD±R media was burned by using the OverSpeed function.
