Build speeds different for different media?

Something I've noticed about the write speeds for Building images for DVD versus Blu-Ray sized images.

 

 

For instance, when I build a DVD-9 sized image, the write rate to HD is about 12x on average.  When I build a BD-R sized image, the write rate to HD is about 6x.

 

 

Is this expected behavior for ImgBurn?

Yes and no.... 1x DVD is different to 1x BD. (~1.3MiB/s vs ~4MiB/s)

 

Look at the actual KiB/s though, they should be approx the same if using the same source/dest devices and approx the same files/file sizes.

I can't complain about the speeds, actually.    A DVD-R image writes in like 2 minutes.  A DVD-9 in 4.  A full BD-R in 10.

Sometimes, I get some really weird high rates.  Like when I'm writing VIDEO_TS folders with things like .AVI files added to the root directory.  When it gets to the extra files, I sometimes get things like 128x.
