DVD-R/RW Writing performance
DVD-R media compatibility and write quality:
In these tests we will be using a Lite-On SHW-16H5S with firmware LS0T along with K-Probe to measure the disc quality. We will also be using the NEC ND-3540A with firmware 1.03 along with CD-Speed for our read-back tests.
For these DVD writing tests, the Plextor PX-755A was set to the following.
⋅
Power Rec
on
⋅
Auto Strategy
on
⋅
All media had
been stored in the Auto Strategy database prior to writing the
disc.

PI errors are just within specification, and a cluster of PIF errors near the end of the disc are worrying. The read-back test is perfect. The result is ok, but not what we expected from this very good quality media.

PI levels are high near the end of the disc but are within specification. PIF error levels are low and our read-back test is perfect; a good result.

The PI error levels are quite high throughout the burn and PIF levels are fairly constant throughout the burn, but all well within specification. The read-back test is perfect and the result is good.

PI errors are rising towards the end of the disc, but are well within specification. PIF errors values are low, but fairly constant throughout the disc. The result is good.
DVD-ReWritable media:
We used the same testing
procedures as we did for DVD-R media.
Our obtained results can be seen

The Plextor PX-755A has handled the Verbatim DVD-RW media well. A very good result.
To sum it up: Overall, the write quality is generally good/very good on DVD-R and DVD-RW media.
