Nec 4550 vs Nec3500

I think that nec4550A can be better than nec3500A for burning, only need’s good strategies for some media. Look at this:

  1. scan of DVD+RW Philips 041 (4x Xidex branded), burned with nec4550A 1.06 (original version), scaned with nec3540A 1.W7 at 5x, 1ECC.
    Result is very good for this media, i have much worst result on Nec3540. And this result even better than for Nec3500 2.TG.
  2. scan DVD-RW TDK502sakuM3, (2x TDK branded), burned with nec4550A 1.06 (original version), scaned with nec3540A 1.W7 at 5x, 1ECC. + scans for nec3540 1.W7 and 3500 2.TG
    Better than 3540 and almost same as nec3500 (less PIE but more PIF)

Some comparing to nec3540 :

  1. scan of DVD+RW MBIPG101 W03 (2,4x L-pro branded), burned with nec4550A 1.06 (original version), scaned with nec3540A 1.W7 at 5x, 1ECC.
  2. scan of DVD+RW MBIPG101 W03 (2,4x L-pro branded), burned & scaned with nec3540A 1.W7 at 5x, 1ECC.



  1. scan of DVD+RW MKM A02 (4x Verbatim branded), burned with nec4550A 1.06 (original version), scaned with nec3540A 1.W7 at 5x, 1ECC.
  2. scan of DVD+RW MKM A02 (4x Verbatim branded), burned & scaned with nec3540A 1.W7 at 5x, 1ECC.
  3. scan of DVD+RW MKM A02 (4x Verbatim branded), burned with nec3500A 2.TG, scaned with nec3540A 1.W7 at 5x, 1ECC.
    Nec 3540 have a real serious problems with this media, Nec4550 not excellent but not so bad as 3540. I guess that it’s crap media, all drives shows high PIF level.




I would have to say that a comparison of these two drives would be interesting and I would predict an overwhelming win by the 3500. NEC has yet to make a drive since then that has done as well.

Any scans should be done on a Liteon though, due to problems with NEC scanning.

I remember quality of 1st firmware Nec3500 2.16, it was real CRAP :Z . Nec4550 have better quality with 1st firmware than nec3500 with 1st firmware.
I know about bad scans with Nec, but unfortunately i haven’t LiteON drive. Best what i have for scanning is nec3540.

burned with nec3500 2.16


I am basing my assumptions on the quality of the firmware for the 3520 as well as the 3540, neither of which has been nearly as good as the 3500 2.18. Fairly quickly, the 3500 was a great burner; it took barely 3 months to get to 2.18. While the 3520 came close it still is not as good and the 3540 still has quite a ways to go; the original firmware was March 2005 and there are still problems.

Of course this could be different with the 4550. Who knows, as we are both just guessing.

BTW, the original firmware for the 3500 was 2.06, released 7/23/04.

I agree with problems with 3540, but it looks like that 4550 and 3540 have different mechanical part (not only different chipset). nec3540 is good reader, much better than other nec’s (some reading test here http://club.cdfreaks.com/showthread.php?t=154587). Reading quality with 4550 very similar to 3500, maybe they have same mechanical part.
maybe:
good reader=bad burner & bad reader=good burner :bigsmile:
interesting theory… :slight_smile:
