Nu Tech DDW-081: More DVD+R madness

Above is an 8X DVD+R burn with some MMC media (CD Speed reports CLV instead of Z-CLV). Notice that the strategy is very similar to Plextor's; the burn starts at 6X and then adjusts to 8X Z-CLV. However, it looks apparent that there are some stability issues at that speed, since we see several stop gaps in the burn. Perhaps we are seeing the 4X Nexperia PNX7850 chipset showing its incapability to run out of spec.
Below are the CD-R, CD+RW, DVD+R and DVD+RW speed tests. We used DVD/CD Speed with the same configuration as the previous test.
| Label | Rating | Average Write | Length | Mode |
| Ritek 97m31s01f (Cyanine AZO) | 52X CDR | 23.48X | 74:43.00 | P-CAV |
| Imation | 52X CDR | 29.32X | 74:43.00 | P-CAV |
| Mitsubishi 97m23s24f | 24X CDRW | 9.95X | 74:43.00 | CLV |
| RICOHJPN R00-01 (Imation) | 4X DVD+R | 7.72X | 4.38GB | Z-CLV |
| FujiFilm | 2.4X DVD+R | 2.36X | 4.38GB | P-CAV |
| YUDEN000T01 | 4X DVD+R | 3.91X | 4.38GB | P-CAV |
| MCC 002 | 4X DVD+R | 7.62X | 4.38GB | Z-CLV |
| Ricoh RICOHJPN | 2.4X DVD+RW | 2.37X | 4.38GB | CLV |
| PHILIPS 041 | 4X DVD+RW | 3.92X | 4.38GB | P-CAV |
| RICOHJPR01 | 4X DVD+R | 7.63X | 4.38GB | Z-CLV |
Compatibility on the drive was a little sporadic. Some of our Ricoh based FujiFilm, which is rated for 4X, only trickled out of the burner at 2.4X. Fortunately, this was the only media that wouldn't burn as advertised. We are not 100% sure why this happened.
Bit setting does not seem possible with this drive, which is a shame. Most drives based on Ricoh design are capable of bit setting the book mode to other formats. We have heard conflicting results claiming that this particular drive does; although with Nero, it seemed not possible. Using BenQ's bit setting tool was not supported by the drive.

Is it possible to post the latest firmware? There is no mention of a firmware update on the Nu Tech site. If you can't post it, maybe you can leverage your contact with them to get it up on their web site.Anonymous User - Wednesday, October 22, 2003 - link
How about some DVD-ROM and DVD-Video read speed tests? DAE anyone?Anonymous User - Wednesday, October 22, 2003 - link
The MCC 002 discs are technically rated at only 4x. So yes, it can write to some 4x media at 8x.Anonymous User - Wednesday, October 22, 2003 - link
"Our main concerns stem from the lack of 8X DVD+R media. While our current champion, the Plextor 708A, had no problems burning several brands of 4X media at 8X, the DDW-081 will only burn 8X certified media at 8X. The lack of bitsetting capabilities for the drive seemed disappointing also. Granted, our Plextor 708A does not support bitsetting either, but it does support DVD-R burn capabilities."Did you try the DVD+R 4X Verbatim media that came with the drive....I did and it allowed me to burn @ 8X :)
See here for some results:
