Write Quality Tests MKM 001
Dual layer media follows the same rules as single layer, but there are certain points on the disc where errors are known to occur the most. We have noticed that the part of the disc where the transition from layer to layer happens is where the PO errors have shown up. Our results are as follows:
We didn't have much luck getting dual layer media both to burn on all drives, since the Sony DRU-710A and MSI DR16-B had trouble writing a successful dual layer disc, and if there was success, to be recognized on the Plextor drive. The DVR-108D and DW1620 came out clean with 0 PO errors each with NEC following with 3 PO errors. The SOHW-1633S was another drive we had luck with, but a successful write was the end of it. PO errors on the dual layer media from that drive hit 192 and were all located between the 2GB and 4GB mark where there were also a few million PI errors!
The DVR-108D performed exceptionally well producing on 546 PI errors on the MKM 001 media. NEC followed with 261224 PI errors which held it and the Pioneer unit at the top two spots.
The Q-Tools screenshot of LiteOn's burn shows the majority PI errors between the 2GB and 4GB range.
It's too bad that there were only 4 drives on which we could test write qualities. Hopefully, future firmware releases will fix compatibility issues on the drives that we have tested in order for media to be recognized correctly on a wider range of hardware.

I think some are forgeting that testing these things doesn't happen over night. Between other reviews, news, etc and normal working hours it could be quite easy to have a new firmware come out after you've already tested.For the plextor drive it does seem like bestbuy's website has them in stock for $140 with a $30 MIR. So is the extra's of a plextor worth the extra $30 to $40?

I notice with the Lite-On 1633 drive you was for the roundup still had the original firmware,there`s a new firmware "BSOK" update out dated 26th OCT that has "matched more media" support.I happen to own the external version and can say it`s very quiet while burning and also in playback mode,the only noisy thing is the tray when ejecting IMHO,btw I think it`s a great burner very low P1/PO errors and no bad burns so far.

What is interesting is I just bought a Plextor PX-716a at Best Buy this last week. It works GREAT so far. Will do more testing but so far it's fast and reliable. It is at UDMA 4 by the way. It flys.It came with both a White and Black face and door.

er, Nov 8 for PREORDERapparently they are still working out bugs
I note in the specs that the drive will run in UltraUDMA mode 4 or 66MB/sec in addition to PIO
Interesting

Can anybody comment on the noise level of any of these drives (esp. the NEC, BenQ and Pioneer)? I'd like to throw one of these in a sff and use it as a htpc, so a loud drive spinning sound would really bother me.KristopherKubicki - Monday, November 1, 2004 - link
Maverick215: Feel free to download the .zip files with all of the disc quality q-tools and nero tests.techfuzz: When we tested the drive 2.16 was the newest available.
As for the BenQ drive, we tested with the newest firmware possible.

From page 9 (Sony Review) <<...dual layer burners are pseudonymous with 16X burners...>>I think the word you're looking for is 'synonymous', not 'pseudonymous'. A pseudonym means 'a fake name', whereas a synonym means 'basically the same thing'. However, in Sony's case, pseudonym may be more accurate.

I find the average write speed of 11.88x for the NEC on 8x DVD±R MCC media very hard to believe. It would need to support them at max 16x speed to get this average speed and it does not, unless you've used a hacked firmware.I also doubt that the Pioneer is faster than the BenQ @12x on 8x MCC DVD+R if you compare the actual write time. Other tests have shown the BenQ to be a good 30 seconds faster than the Pioneer at 12x thanks to PCAV write tech (vs. ZCLV).
