Burn speed question

[costanza]

I read here recently where someone was recommending burning at the disc's maximum rated speed rather than slower (i.e., burning an 8x DVD-R at 8x instead of at 4x). I thought you should always burn at a slower speed if you're really concerned with making as perfect a disc as possible. Am I missing something?

Very good burners(and firmwares) in the right computer(hardware&software)
using premium media can burn better at 8x than 4x. I have never seen
a 16x burn that was better than an 8x tho. Everyone needs to find what
works for them.

As chewy stated it depends on many factors, the suggested 4X burn speed is just that a suggestion. Each system configuration will be different, so experiment with yours to see what the optimal burn speed is.

do quality test for every single one then you know which one is best for you, which media, speed your burner like

What do you mean by "better", and what makes burning them at the faster speed "better" vs. slower? I could see where maybe on really good equipment there would perhaps be no difference if you wanted to burn faster, but what makes burning quality "worse" on the same equipment if you burn at a slower speed?

I'm sure DD has their own quality scanning thread but I don't know where to find it, so here is the one that I do know about. Take what Chewy said into consideration while reading this because the poster is adamant about 4X burning, but he may not have the same burner and system specs as you.

I bought a benq 1620 so I could do fairly high quality scans of burns,
then I tested a lot of disks. It's not a user friendly field. Took months to get
a hint of what's going on with burns.

Let me re-phrase my question... If you are saying that (based on your equipment combination) you could get a "better" result from burning at a faster speed, what exactly is happening when you are using good quality discs and burner, but get a worse result when burning an 8x DVD at 4x speed instead of 8x speed? Understand?

I'm not sure to have understand your question.

If you burn an high certified media at a too low speed, you have a very high probability to obtain bad results because the dye of these media is suited to be burned at high speeds. It's a chemical problem: the high speed dye must be burned at high speed, else will give bad results.

It's like to have a sport car: their engines are specifically designed to work at high speed, and if you drive such a car at a too low speed, you'll ruin the engine.

For DVDs the best speed is "around" their certified speed. So a 8x media can be burned with good quality @8x or @4x (some also @12x), because these speed are all around certified speed.

The problem is worst when burning 16x certified media @4x: this speed is not around certified speed, and this have a very high probability to create coasters.

Do this answer to your question? Sorry for my grammar errors (english is not my primary language).

let's just say this, and I know it from my tests, on premium media and a good 16x burner, the best results are obtained when I burn at 8x. At 4x it can be as good but never better. At 16x it's always worse. Since 8x takes 8-9 minutes and 4x takes 14-16 minutes, I choose the best of both worlds.

Okay. That answers my question. I'm not doubting you, but do you have any "white paper" data to back it up? In other words, where did you get this info? Thanks!

Nero speed test and you have to do for yourself base on your system, burners and medias

[Chewy]

Read for about 3 months(2-3 hours a week) over a cdfreaks and you'll learn more than any white paper, real world data by geeks who collect burners like it's a hobby or a sport(both apply). Watch out it's contagious. Geno and I have caught it.

But both of you are really good & knowledgable at it too.
