Burning BD-R - shouldn't burning at 12x be twice as fast as 6x?

[Carla_Boots]

I am a newbie to burning BD-R.   Just bought a LG WH16NS40 16X BD-R burner.  

It was only $59.99 from Newegg during a sale.... price too good to pass up.   

 

I also got a 50-disc spindle of Verbatim 25GB 6X inkjet printable BD-R.

 

I fired up ImgBurn and the default burning speed was 6X.  I burned several discs

and everything went smoothly.  I verified the burned discs on another computer

and they checked out fine.

 

Next, I decided to up the speed to MAX.  ImgBurn started burning at 12x.  

After several discs, everything looked great.  (again, verified the data on

another computer)

 

Here's something I don't quite understand.  When I burned roughly 21GB of

data on the BD-R at 6X, ImgBurn reported burning time of 16 minutes.

When I burned the identical data at 12X, it reported 11 minutes. That's only

5 minutes faster.  Shouldn't burning at 12X take half the time, which is 8

minutes?  

 

Thnaks!

No, the speed ramps up over the entire disc. It'll only reach max speed right at the end.

Thanks!

 

When I use Verbatim 6X BD-R, ImgBurn shows it capable of 12X max burning speed.

 

Which burning speed is better? 6X or 12X?   I don't really care about saving time...

Sorry, I can't answer that question. You'd have to burn a few discs at each speed and then scan them to check the quality. It really depends on the drive and firmware as to which speed gives the best results.
