Not sure if I got the right forum, hope so. I’m not really trying to use this as my own personal troubleshooting forum or anything and i’ll be viewing the forums more often now.
First off, I have about 25 single duplication units and about 6 5-6 drive duplication towers. In the past I used all Pioneer burners in them but once when 16x burners came out I got 5 new ones and had a bad experience with them burning DVD-R Ritek media, so I switched to NEC and haven’t switched since.
All the towers use Acard controllers. 100% of them use Lite-ON and Asus drives (were are mostly Lite-On made anyway). Most are 167T and E616 drives.
Recently I ordered about 6 new 1-2 Duplication units. The drives in them were Sony DDU-1615 DVD-ROMS which were just just rebadged Lite-ON 1609SVs.
Here’s the very strange thing. I do a on the fly copy from one dvd-rom to the NEC 3550A burner. I burn at 8x and have used 4 different types of media and it’s definitely not that. It takes over 15-17 minutes to do one copy at 8X! This is without any verification or testing etc. I even upgraded to the latest firmware for the drive (with the speed unlock etc).
I thought it was the new unit, so i put the dvd-rom in another tower and same thing! I tried an Asus 616E in both and it’ll both do on the fly copies in 9 1/2 minutes or 10!
I’m so dissappointed! I have a Lite-ON 16P9SV as my main DVD-ROM in my pc and love it. I was reaching 14,700KB/sec last night with DVD dEcryptor on a DVD9 disc. Not bad, but not quite as good as those BenQ drives. I now want one so bad!!
I can’t believe how this drive can rip so fast, but yet when I asked it to do on-the-fly copies it goes soooo slow. I even used the same source media when I tried an on-the-fly copy with different towers.
So I did a dvd-rom to dvd-r copy and I was shocked to see that even my current setup took 16-17 minutes! This is just not right!
I guess i’ll pull out all my DDu-1615/16P9SV drives and switch back over to Asus 616A dvd-roms. It’s such a pain though.
Any idea why some dvd-rom are just so incredibly slow at doing on the fly copies? I even tried a new source media. The source was taiyo yuden media. Even tried new cables and hours of other testing. I think I read that the buffer was only 256k or so, maybe that doesn’t help me much?
I’m not that impressed with the NEC 3550A drives lately. I might switch back to Pioneer drives. Do you think the BenQ drives would be good for duplication systems? Do they work well with most DVD-R media? I use TDK 16x media (CMC MAG03? Scores a 95% in nero) and Taiyo Yuden. BenQ doesn’t seem to be very common in the USA where I am. Almost nobody I know who has a PC has heard of them! Perhaps they’re most common in europe?
Anyway, maybe someone has some ideas for me. If not, no big deal. Usually Lite-ON drives are good, but 17 minutes for an on-the-fly copy is just so terrible to me! My 4x burner burns faster than that!
