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.
8X DVD+R Writing Speed
- BenQ 8X DVD+R @ 12X
- Bulkpaq 8X DVD+R @ 8X
- Datasafe 8X DVD+R @ 8X
- Datawrite Titanium 8X DVD+R @ 12X
- Maxell 8X DVD+R @ 8X
- Optodisc 8X DVD+R @ 8X
- Ridisc 8X DVD+R @ 8X
- TY 8X DVD+R @ 16X
- Summary
At lower burning speeds and 8X in specific the drive managed to create some good media, while at this speed we also had some overspeed burns, such as with the Datawrite burned at 12X and the TY media burned at 16X, both reporting good quality burns, according to the CDSpeed and PlexPro utilities.
