Write Quality Tests MCC 004
We read the 16X MCC 004 media in our Plextor drive with Q-Tools to check for errors that the various burners may have written. Again, only these drives were able to write to the 16X media properly for the PX712A to read.As we described in our second section, PO errors are the ones to look for when testing certain types of discs with burners. These errors can render a disc unreadable and should be minded if they exist in the double digits or even too often in a small area for them to be corrected. The media written with the four drives that we were able to read with Q-Tools were virtually PO error free.
Shown below are the results for those drives that were capable of writing to MCC 004 16X media successfully.
It is obvious that there were no problems writing readable discs with the Sony, LG, Pioneer, and Nu Tech drives.
PI errors are not as ruthless as PO errors. For example, though Q-Tools has read 404,647 errors on the MCC 004 media written with the 710A, it doesn't mean that the disc is completely bad. Most of these errors were found towards the end of the disc, but data can still be read off that portion of the media.

The screenshots above show that the DRU-710A has performed a successful write, but the read back on the Sony unit towards the end of the disc was a bit shaky. We mentioned earlier how media is prone to warping on the outer portions and this is where most of the errors can occur. Plextor Q-Tools confirms that by detecting over 400,000 PI errors within the last 1GB or so written to the MCC 004 disc. Take a look at the graphs from LG's GSA-4160B...

Again, about 99.9% of the PI errors are at the end of the disc. The Nero screenshots show nothing in terms of trouble with writing or reading from the disc on the LG drive, mainly because it was able to correct these errors with ease.
The DW1620 and DVR-108D have done a better job at writing to the media with 6052 and 5614 PI errors respectively. We're disappointed that the other drives could not write to the MCC 004 media or could not be read with Q-Tools like the burn LiteOn's SOHW-1633S performed.

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).
