Writing Quality Tests

The following screenshots present the PI/PO results for various DVD-R and DVD-RW media, recorded with the DVR-320-S.

The software used for the measurements was Nero CDspeed (v3.21) and Plextools Professional v2.16. The ECC was set to 8 and the reading drive was the Plextor PX-712A with firmware v1.05. The specific methodology is very dependent on the drive used as a reader, while the reliability of the PI/PO provided output is also not technically confirmed. Consequently, we could not safely come up with any conclusions, but still, we did make a comparison of the drive's behavior when using various DVD recordable/rewritable media.

BeAll G40001 DVD-R

BenQ SONY04D1 DVD-R

Intenso ProdiscS03 DVD-R

Mam 4XG02 DVD-R

Generally, the drive offers good writing quality. However, there were instances of increased PI/PO levels, but the device managed to correct the errors.
