25. Conclusion
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.
8X DVD-R Writing Speed
- 3A 8X DVD-R @ 8X
- BenQ 8X DVD-R @ 8X
- Bulkpaq 8X DVD-R @ 8X
- Datawrite 8X DVD-R @ 8X
- MMore 8X DVD-R @ 8X
- Prodisc 8X DVD-R @ 8X
- Prodisc 8X DVD-R @ 8X
- Ridisc Red 8X DVD-R @ 8X
- Summary
Low error rates in almost all cases, but with specific media the LiteOn reader found it hard going, hence the speed drops in the CDSpeed graphs. Once again we repeated the CDSpeed reading tests with a second LiteOn reader, but still the same performance.
