In order to test the writing quality and readability of the burned media, we used two readers equipped with two software applications:

- The LiteON SOHD-167T with patched firmware being able to read DVD5 up to 16X CAV and DVD9 up to 10X CAV. For the transfer rate tests we used the latest Nero CDSpeed version.

- The Plextor PX-716A with the latest available firmware. For scanning the disc, we used the latest PlexTools version at 2X CLV reading speed, BURST mode, with middle accuracy.

In general, a "perfect" disc should have a smooth reading curve, very low PIE/POE and zero (0) POF error rates. Most times however, even though a disc has very low PIE/POE error rates, the reading curve may not be smooth containing dropoffs. Due to the fact that we oversped the reading capabilities of the LiteON SOHD-167T, such drops are expected, especially near the outer area of the disc.

The measurements below should not be taken as the absolute criterion of the burning quality, but as an indication level.

16X DVD+R Writing Speed

- BenQ 16X DVD+R @ 16X

- Optodisc 16X DVD+R @ 16X

- Philips 16X DVD+R @ 16X

- Plextor 16X DVD+R @ 16X

- Prodisc(R05) 16X DVD+R @ 16X

- Prodisc(R04) 16X DVD+R @ 16X

- Ricoh 16X DVD+R @ 12X

- Ridisc 16X DVD+R @ 16X

- Traxdata 16X DVD+R @ 16X

- Verbatim 16X DVD+R @ 16X

- Summary

According to CDSpeed and Plextools Quality checks, the writing quality was good with most of the tested media. Almost all media produced low error values but the speed graphs could be smoother in some cases. If we compare it to the PX-750A, we could say that the burning quality has undergone serious improvement, at least with 16X media. Three media were added since the Preview released a few days ago, those of Traxdata, Prodisc (R04) and Philips. Only Traxdata media reported average quality while the other two media were of good quality.
