Windows Disc Image Burner is faster than ImgBurn?

Recommended Posts

Hey,

 

I don't know what am I doing wrong, or how is this possible, but I took time how long it took to erase my 2x 4.7GB DVD-RW disc and write the latest testing Dual Core iso of Archlinux with both ImgBurn and Windows' own Disc Burner and found out that ImgBurn did this in 8:18 (mins:secs), while Windows' own decided to take only 6:46.

 

I even re-wrote(/erased) the disc two times with both burners - results were still the same. No anti-viruses, no old firmwares, no nothing. My system is a up-to-date Win 7 (SP1) with the latest version of ImgBurn (2.5.6.0).

 

How is this even possible?

ImgBurn uses the DAO/SAO write type by default and drives tend to burn a minimum of 1GB to DVDs when that's being used - it makes the disc more compatible.

 

If a program were to use the Incremental write type instead and the drive then only burns the 700MB image (without padding to 1GB), that would explain why it takes less time.

 

So it's not actually faster (that's impossible as the drive controls the speed), it's just doing things differently.

Interestiiing... I re-did the write with "Write Type" set to "Incremental" and true enough, ImgBurn was actually 16 secs faster than the Windows' builtin one.

 

Impressive. That didn't take too long from you.

Hmm, is there reasons other than compatibility?

 

I've now burnt five DVDs with incremental and they all seem to work just fine. I don't plan to use these with any other PC anyway.

I never do any real testing with non-default settings. The defaults are what I use day in, day out - and have done so for about 5 years.

 

Do you really burn enough undersized images to DVD-RW disc to make it worth the risk?

 

Are you really sat there tapping your fingers for the extra 2 minutes that DAO/SAO could take?

 

It's totally your call, I'm just saying I wouldn't do it.

Of course. But what is this "risk" then? I understand you don't recommend doing it but is there a real risk in it, eg. corrupting the DVD?

 

If compatibility is all it eliminates, I can live with that.

The risk is that the software hasn't been fully tested with it.

 

Obviously you want to stick with it on Incremental so just do that.

 

If you run into problems with other things, you'll know to switch back.
