even if i have my 48x cd writer i only burn at 16x for data readability... at what speed do you guys burn?

As long as the writing quality is good at the end, I burn as fast as possible.

how do you check your burning quality? this is strange... when i do scandisk using Nero CD Speed tool, i get yellow blocks when i use my DVD-ROM to do the testing, but when i use the cd-writer for testing, all the blocks are green... who's right? i know cd-writers are not reliable for testing since it's a common case where cd-r is only readable on cd-writer and not on cd-rom in cases of bad burns...

Not all drives are able to report C2 errors (not even all brand new ones like the Mitsumi 54/32/54 :evil: - see Ian's review). In that case, CD Speed will just show green blocks unless it notices unreadable sectors (on a data disk) which will be red. The Nero InfoTool will tell you if your drive can report C2 errors.

Incidentally- I burn audio (mostly) at 16x and evrything else at max. And I test every disk (normally with KProbe)!!

Most all the DVD-ROM drives report C2 poorly.
I burn everything at 40x, and the quality is awesome on the 52x LiteOn. Of course I only use 48x+ media.

I burn at top speed for data. 32X for Audio on a 48X Burner. 40X for Audio on a 52X Burner.

I burn at my drive's max speed as long as the media can support it. I also test most discs with KProbe.

I burn at the fastest speed that the drive supports as long as the media also supports that speed.

i no longer rely on the rated speed of the media. i encounter situations where sony cd-r can't be produced at good readability when i burn it above 24x on lite-on cd writers. even if the rated speed of that sony cd-r is 32x!

If I don't care, I burn the disc at the fastest speed I know it can handle as opposed to what it is "certified" for. If I *DO CARE* about the disc, then I burn it at 12x or 16x depending on what the maximum speed that is still using a CLV writing method is. Generally I write at 16x unless I'm in a rush. and Like many others here I ALWAYS test my CD-Rs, using K-Probe :D

48x on my TDK using 48x Fuji media. :D

Ditto. How do I know? You guessed it. :)

Burning Speed

Let's say I burn a 48x rated CD-R music disc at 48x speed on my Memorex 52MAXX drive. Then, I burn a second 48x rated CD-R music disc (same music) at 24x. I run KProbe on each of the two discs and say I find that the number of C1 and C2 errors on each disc is roughly the same. Is that enough to tell me that I should burn at 48x? Or do I also need to listen to both discs on various CD players to determine which burn speed is better?

It would be best to also do a few listening test in the actual players you intend to use. Audio CD players, particularly older ones, are often picky about the CD-R media they will play. They may like one dye type or media brand and not another. Or they may like one burning speed and not another. They may even like CD-Rs burned in one drive and not another. So it is really best to do some "proof is in the pudding" tests before committing to burn a lot of CDs.

you're also COMPLETELY ignoring jitter errors....

I probably represent the conservative and diminishing minority here, but...

I burn at the slowest possible speed that is still convenient for my purposes and which offers gains in burn quality over a higher speed.

IN audio this means (on my gear) 4x.

With data, on most CDs I burn at 16x or even at 24x.

And it's not about bad media as I use the best media I can possibly find (sans medical grade CDRs). Nor is it about the quality of drives (Yamaha CRW3200, Plextor and LiteOn).

It's about having been burnt once and being twice shy.

I've been burning since the beginning of 90s and some of the later burnt stuff has failed either to a selection of bad media or burn speed (or both). At the same time, stuff that is 10 years old reads perfectly.

Ok, I could (if I was even more conservative and had more time) keep on backing up the old media to new burns, but I'm still not doing that on mass scale.

So, for the stuff that I want to be able to read 10+ years into the future I write as slow as possible (if there are gains and not losses in burn quality).

But that's just me.

halc

Maximum allowable speed that Smartburn will let me go. Always check disc with kprobe.

Halc And what if I told you that you are creating higher error rates with the low-speed burn?

Depends on the media I'm using.

Some 48x discs only go to 32x before Smart Burn kicks in. Others are fine @ 52x.

Having said that:
Data as fast as possible.
Audio 8x - 16x.

Overburning (ie: 99 minute discs) usually 4x - 8x for both data & audio. If I'm truely overburning a 99 minute disc ( up to 101 minutes etc) then only 4x.

from my experience, and my testing 99% of the time, 16x will yield the best results. Now on some really good media, oyou WILL get lower C1/C2 errors at some faster speeds However I would never push faater then 40x...I think Yamaha was onto something when they stopped producing drives at the 44x mark.

After having read the jitter testing done at CDRinfo.com, I have to seriously consider burning faster then 24x to be a really bad idea for playback on some systems. Generally speaking, if you burn a CD-R faster then 24x, you wil usually end up with a CD-R that has higher jitter errors then allowed by CD standards. This is not something I want, and I believe it is likely to cause problems with compatability with some players.

with 99min CD-Rs, I will never burn them at ANY other speed then 12x or 16x. I did some testing of my Ritek 99min CD-Rs, and I tested all the burn speeds from 4x to 48x with at least one CD-R each (though in a couple cases more then one) and there was a VERY deffinate quality curve. The quality peaks very deffintaly right at 12x and 16x, and has a significant raise at 8x. Don't even think about 4x or 24x, and you probably won't be able to read the disc if you burn it at 32x, due to the incredibly high C1/C2 errors.

Of course some drives can only overburn properly at the lower speeds, so this kiinda leaves you in a ight spot!

I always burn my 99's at either 4x or 8x.

Came across this old topic, and just wanted to share one thought that has crossed my mind lately.. don't you guys find it quite funny, and funny in a sad way, that even though the speeds reached 48x, we still have to do the testing afterwards - since we can't trust the media. Which means whole process takes like 2 or 3 times more than burning itself.. Which means we're basicly at 16x speeds..

you don't *have* to test your CDs, it's a luxery :wink:

There's also no logic to the apparent assumpion that burning at 16x does not also require error testing. In fact, the opposite may be true.

Well maybe not 16x, but say for example 40x - I have yet to come across a coaster when burning 52x media with 52x writer at 40x.
