AOpen DDW8800
The second drive in our roundup to sport the NEC D63630GM chipset is the AOpen DDW8800. This is the same chipset used in the NEC 2500A, ASUS DRW-0804P and Pioneer 107D. For all intents and purposes, the AOpen DDW8800 and NEC 2500A are identical. Even when it comes to manners of price, the NEC 2500A and AOpen DDW8800 are within a dollar or two of each other. There are some slight differences between the DDW8800 and NEC 2500A, including pickup/servo and construction.| AOpen DDW8800 DVD-/+R Drive | |
| Interface | IDE |
| CD Write Speed | 32X, 24X (Z-CLV) 16X, 12X, 8X, 4X (CLV) |
| CD Rewrite Speed | 16X, 12X, 8X, 4X (CLV) |
| CD Read Speed | 40X Max (CAV) |
| DVD-R Write Speed | 8X (Z-CLV) 4X, 2X (CLV) |
| DVD-RW Rewrite Speed | 4X, 2X, 1X (CLV) |
| DVD+R Write Speed | 8X (Z-CLV) 4X, 2X (CLV) |
| DVD+RW Rewrite Speed | 4X, 2.4X (CLV) |
| DVD Read Speed | 12X Max (16,620KB/s) (CAV) |
| Supported Modes | DAO / DAO-RAW 16 & 96 TAO SAO / SAO 16 & 96 Packet Write Multi-Session |
| Supported Formats | DVD+R (DAO, incremental, seq) DVD+RW (random) DVD-R (DAO, incremental, seq) DVD-RW (restricted overwrite) CD-R, CD-RW, CD-ROM, CD-DA, CD-ROM XA, Mixed Mode, CD Extra Photo CD, CD Text, Bootable CD, UDF |
| Access Time | CD: 120ms DVD: 140ms |
| Buffer | 2MB |
Even though the AOpen DDW8800 shares an identical chipset with the ASUS DRW-0804P, it carries a higher CDR write speed, and a lower CDRW speed. Whether this is due to royalty issues or minor adjustments to the pickup, it is not clear.
There are several other drives that use the same NEC D63630GM (found in this drive) and also use the NEC assembly. We would expect similar performance of the AOpen DDW8800 with:
- NEC 2500A
- TDK AID+880

Nu has posted the official firmware upgrade B373, I hope this one is as good or better than the unofficial B372. I bought this drive and hope I have as good results as Anand Tech. With it's ability to write 8 times on 4 times Media and it's speed and error rate being almost as good as the more expensive drives it seemed a bargain.mcveigh - Sunday, May 2, 2004 - link
21:the Nu models do as well or better than everyone else and at the lowest price point.
why shouldn't they win?

Jeff7181: I think there is a way to get it to scale proper. I will do that for the next review.Kristopher

Seems to me that all of the DVD writer reviews lately on Anandtech seem to favor the Nutech product. I don't see a reason from these results to pick that drive over any of the others. There's nothing that makes it anything special, and it certainly doesn't deserve an award over the other drives.Another vote for total write times and for not claiming that all drives with the same chipset will perform similarly. Too many variables. At least test with more media types, like TY and Optodisc. Cheapies like Princo appeal to many as well.

The Write Quality graphs are very misleading/hard to read since they are all on different scales... makes on look like crap until you realize you're looking at a 0 - 10 scale rather than 0 - 70. Anything you can do about that or are you just stuck displaying what the crappy software showed you?KristopherKubicki - Thursday, April 29, 2004 - link
This was all commented on in the article. The 708A and the 2500A also use radically different pickups and servos. But then again, i never claimed those two were similar in the review either.Belzer: most of those drives i pointed out were clearly rebadges.

Belzer,yes. Maybe I should have rephrased my statement, as MAXIMUM burning speed. Yep, it also depends on the burn strategy employed.CrazeeHorse - Thursday, April 29, 2004 - link

"If you mean burn speed, of course it will be similar in different drives that use the same chipset, as their burn speeds are defined by the chipset!"Uhm, no! Burn speed also depends very much on the write strategies implemented in the firmware. For example NEC ND-2500A and Pioneer DVR-A07 use the same chipset. The NEC uses a 4x-6x-8x Z-CLV technique for 8x burns, the Pioneer uses a 6x-8x Z-CLV technique and is faster.
Drives with the same chipset can have very different properties, only complete rebadged drives will have the same properties.
