Perhaps most of us are not that familiar with Nu Technology (aka Nu Tech New), but virtually everyone has heard of their parent company, Quanta Storage Inc. QSI is one of the larger and older optical OEM producers for several US based system builders. Unfortunately for QSI, selling to retail stores and OEM clients began to infringe on their system components, and thus, Nu Technology was born. Nu Technology went into business officially in May 2003 as the retail branch of QSI, and already they have an extensive product line.

This week, we were fortunate enough to take a look at Nu Tech's DDW-081, a DVD+R/W only drive with CDRW capabilities based on the Philips Nexperia chipset. Even though this is one of the first drives to debut with 8X DVD+R, is it enough to dethrone our current champion, the Plextor 708A? Remember, our 708A is a dual format, but limited in CDR capabilities and bundled features.

There are two things I'd like to point out. The first being DiskInfoPro identified the MCC disk as 8X before it was burned. Furthermore, the FujiFilm disk was identified as 4X on the box, and 4X in DiskInfoPro before it was burned.

#12: Thank you for the updated link. The PDF I recieved was straight from QSI and I was unaware there was an update on the chipset.

Cheers,

Kristopher

Yes... MMC 02 is capable of 8x with that drive. That's why your utility is saying that. However, that doesn't mean that Verbatim/Mitsu. actually rates it at that speed.

One more thing, in the review you claim that the PNX7850 chipset does not support 8x speed. Not true, it does: http://www.semiconductors.philips.com/acrobat/lite...
It was only early versions that didn't support 8x. The PDF you link to is for the complete reference design where the Philips OPU 66.20 limits the speed to 4x (I assume QSI uses a different PUH).

Then Diskinfo is wrong because MCC 002 (as in Mitsubishi Chemical Corp. and not MMC) DVD+R media are only certified for 4x speed. Use DVDInfoPro or DVDIndentifier instead for checking the media.

#1: We did not have a verbatim disk included. We have a 4X DVD+RW instead. Remember, we had a review sample so ours might have been slightly different. We had to upgrade from QSI firmware just to bring ours to spec with the retail drives.

#2: DiskInfo, kind of a neat utlity, claimed the MMC 02 disk is capable of 4X and 8X.

I uploaded the firmware for anyone who wants to download it. Its on the last page of the article.

Cheers,
