DVD+R Dual Layer
writing speed and compatibility:
The Lite-On SOHW-1653S supports 4x DVD+R Double layer writing speed; let us see how it performs quality and speed wise.
Testing procedure: We created a new compilation using Nero 6 and wrote it using the Disc-at-once writing method:

Verbatim DVD+R9 Double layer 2.4x written at 4x. Total writing time is 27 minutes and 9
seconds.

A slight spike at the layer change but nothing to worry about. All in all a pretty good result.

We could see that there is some slight problems reading back the second layer at full speed with the plextor and that the error level is noticeably higher than for the first layer. But after all, this is one of the few drives that have been able to create a working disc with the ritek DL media.

The discs worked fine in our standalone player, as long as we set the booktype to DVD-ROM.
Summary: The drive has no problems with DVD+R Double layer media, just remember to set the booktype to DVD-ROM.
Before we round off this review, let us run the drive through some advanced tests at next page…




You can back up a whole DVD with all the extra's in 30 to 40 min. Including burn time.




I'm puzzled calling the "Prodye" DVD+R's with Plasmon MID "Low Quality". These discs are top quality, when the drive supports it fully. These discs are actually produced by [url=http://www.3a.net]3A Media[/url] which are great quality media (when properly supported by the firmware!!) . I got results comparable to the well known brands like MCC and Ricoh!


In my book they are low quality comparable the chap ass Hong Kong media and VDSPMSAB media.

But with my custom patches, great results have been achieved already on LiteOn and NEC drives so far (proven by CATS, BenQ Pi/Po/Jitter and LiteOn Kprobe). So it's more LiteOn that doesn't support these media properly then the media itself being crappy.
I've been working with 3A Media for the past 2 years almost and must say they have come a long way, getting a fully working production line with great quality discs from scratch, most of it by trial and error, since Asian companies are not willing at all to share any kind of knowledge.


Cd-r's
Verbatim
Mitsubishi China should be made with MCC technology for verbatim by CMC CHINA.
SAMSUNG cd-r.
Is not made by plasmon.
Good should be manufactured with plasmon stamper or
manufactured probally by Intersonic with plasmon stamper.
Funny that the Daxon Maxell disc's are correctly done. So 2 thumbs for that one.
DVD+R
Conclusion of Ritek media suggests additional tests.
But still it's good you at least mention it.
PHILIPS/CMC. -> you could have copied the coorect info from philips licensing.
(that's something like designed by Philips produced by CMC magnetics.)
Prodye -> 3A made media with Plasmon code as Herrie allready suggests. 3a media is most times quite decent but is very poor supported by most drive manufacturers because it's a european manufacturer !
Then again prodye has been known to also put B graded stuff on the market. So this incombination with the bad compatability might explain the result you are seeing.
The commodore interaxia disc.
Well I could track down the manufacturer for that one.But it's not worth the work. Since most disc's made with interaxia dye technology are not that great.
Also in this case stateing something like made with interaxtia manufactureing technology is better and is probally enough.
Sometimes I have the feeling that the transfer rate test isn't completely taken into account but that could be me who is just a bit more critical as the average user.
Missing media ?
Not really,
Only real media I would like have seen some results off might be RICOH's inversed stack dual layer media.
But ohhwell I know how hard it is to get them and then the fact that the drive isn't on
Ricoh's list so it's ok. that it isn't included.
Another good thing the fact that the name of the manufacturer of the 99 minutes disc was given and the fact that a real disc was burned.
So the end conclusion.
I see that a lot of stuff has improved compared to earlier reviews but still there are some small points on occasions that could be done a little bit better, still this review is allready at a level that only a few other sources can achieve.




Samsung - dunno manufacturer as there is various manufacturers using plasmon stamper/ATIP.
Are 3A the only manufacturer of media with plasmon ADIP?
Transfer rates: as long as speed do not drop too much I consider the result good - as mentioned in the introduction of media quality tests.


).






Let's hope they are faster to send out the 1673S.


which drives you have for your next reviews?






To tell the truth, there is no problems with 16x P-CAV on USB2 and FW due to good profilic firmware from mid december in the case.
Tried the firmware on other profilic cases, but it has copmpatibility issues with some drives (benQ for example), but works great with some
