In order to test the writing quality and readability of the burned media we used two readers 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 overspeed the reading capabilities of the LiteON SOHD-167T, such drops are expected, especially near the outer area of the disc.

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

16X DVD-R Writing Speed

- BenQ 16X DVD-R @ 16X

- Datasafe 16X DVD-R @ 16X

- Datawrite Yellow 16X DVD-R @ 16X

- Maxell 16X DVD-R @ 4X

- MKM 16X DVD-R @ 16X

- Moser 16X DVD-R @ 16X

- Optodisc 16X DVD-R @ 16X

- Philips 16X DVD-R @ 12X

- Prodisc (S05) 16X DVD-R @ 4X

- Prodisc (F02) 16X DVD-R @ 16X

- Ricoh 16X DVD-R @ 16X

- Ridisc 16X DVD-R @ 16X

- Summary

Mixed results for the most part when using 16X-R effective media. Even though with Plextools, most media managed to produce low error values and nice readings, CD-Speed reports otherwise, with erratic graphs and in some cases, incomplete readings. The Almedio Q-check will clarify things, but a firmware upgrade addressing -R burning quality would be most welcomed.
