DVD-R/RW Writing performance
DVD-R media compatibility and write quality:
In these tests we will be using a Lite-On SHW-1635S drive with firmware YS0N 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.

Once again the cluster of PIF errors near the end of the disc is worrying, and we have a small slowdown in our read-back test.

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

Again we have a cluster of PIF errors at the end of the disc, this doesn’t affect the read-back test which is perfect, another good result.

Again we have the PIF cluster near the end of the disc. Overall the error averages for PI/PIF are good, but we see a slowdown in our read-back test. The result is ok but could be better.

The Lite-On SHW-16H5S has handled the Traxdata DVD-RW media well. A very good result.
To sum it up: Overall, the write quality is good on DVD-R and DVD-RW media, but some improvements would be nice with DVD-R.
