#1

i tested the drives with my not favorite but most used media RitekG04 printable, bought at cdrohlinge24.de.

this medias where burned @ 4x speed with the following configurations.

  • Burning Software: Nero 6.3.1.17
  • NEC 2500A F/W original NEC 1.07 FW; Booktype DVD-R
  • NEC 2500A F/W Herrie´s 1.07v2b5; Booktype DVD-R
  • BTC DVDRW 1108IM F/W B228; Booktype DVD-R
  • BTC DVDRW 1108IM F/W B228; Booktype DVD-ROM (i was wondering that Nero is able to set the Booktype to ROM also on -R Medias)

-all medias where scanned with the 1108 IM and Nero CD/DVD Speed 3.10 (Diskquality Test and Transferrate)

Both NEC burned graphs are looking perfect.
The media burned with 1108 and dvd-rom booktype is the most bad, when you compare the results of both 1108 burned medias you can see that the pi errors are a little higher with the dvd-rom bitsetting, average is nearly the same, largest difference @ pi failures dvd rom burn max. 10, average app. 2 times higer.

Both NEC burnes are very good and @ pi failures much better than the BTC ones.




#3

all burned medias are good readable, there are no significant differences between NEC and BTC.



#4

Diskquality on BTC burned medias is not as good as NEC burned (PI errors much higher, PI failures app. 5 to 10 times higher, but on acceptable niveau).
Transferrate shows that all burned medias can be used without problems.

Here are some possible conclusions to this data:
1- The NEC has the best writing quality of any DVD drive.
2- Who cares what the scan looks like, as long as the disc reads ok. If you don’t scan it you’ll never know the difference.
3- NEC makes a better drive than BTC in terms of writing quality. (I doubt anyone can argue that point).
4- Ritek media is inexpensive, but not top quality.
5- BTC needs to work on their write strategies for some media.

Nice data, I’m just not sure what we should take away from your hard work.

Also, I wonder if the results would be any different if the discs were scanned with Kprobe on a LiteOn drive.
