Hello, ppl
I have a simple question

What is the best speed for recording of mp3, wave & other music file types on DVD-R discs ?
I mean the best speed in order to have the best quality of the recorded audio data.
Usually i record with 2x speed, but at the moment i have a bulk of DVD-R discs Verbatim, which minimum speed is 4x

Is it worth to record on 4x, will i have problems with the quality of the record ?

10x

i think lower speed is always better for quality of record

It isn't. For comprehensive information on this matter, I'd head over to the Club Myce forums, there's a lot of talk about it. The general consensus is that very low speeds make the quality of your burn worse, as discs and recorders are tuned for their highest speeds. For the rest, it is black magic and involves a lot of trying and testing.

But that's of no relevance for the occasional burn. Just use the default speed and most of the time, you'll be fine.

The "Quality" of the Audio Data, or the Integrity of the data should be the same as long as the burn validates/verifies as OK (Like the 2nd post said). Else you have a failed burn, and have to burn the disc again.

The media should support the range of speed it specifies, and on any compatible drive. All settings should validate 100%, else there is defect on the media or the drive.

It's possible that a particular media+drive+setting combination may yield a higher percentage of successful burns, but I think nobody holds that data. The amount of media+drive+settings combinations possible is too large to perform those tests. It may very well be that the higher settings of a particular "combination" has been optimized and tested more, or it may be that for some other reason the slower settings are better, or maybe a setting in between! The truth is that nobody knows. And then you buy another brand of media, all that will change again.

In the past, where such high speeds were a breakthrough of both drive and media, the lower settings were considered more "Stable", but that shouldn't be the case today. Note that even though technology has advanced, priority will not always be quality. Some optical media out there focus on price before quality, and before durability.

Last but not least, remember to have backups of your data. Saving data exclusively on 1 piece of optical media, is probably a bad idea. So as long as you keep it on your hard drive or elsewhere, in case the optical media gets scratched over time, then you should be OK.

My own testing, some years ago, showed that even on discs that had no uncorrected errors, there was a huge variation in the number of correctable errors, I took this as an indication of how readable a disc might be on other drives, or in future years, so I wouldn't rely solely on whether or not the disc verifies, especially for archiving purposes.

Of course, for archiving I wouldn't use optical media anyway.
