Technical question:why write rate fluctuates a little

[bfrqrv]

Hai,

 

This is not realy a problem, but more some interest in why my write rate fluctuates a little.

I burn BDR-50 Verbatim (tried another brand also) and the speed is set to 4x. The speed is falling down to 3.9 on one burner, and 3.5 on the other burner. Buffer and device buffer is fine, and I tried to do it from other locations. Because its the same in every situation I suppose its not a problem and its something IMGBURN does. Its about 20 times that the speed is falling down a little for a few seconds. It looks like its writing chapters or something? But maybe someone can tell me what the drive is doing at such a moment.

 

Situation is as followed:

 

 

windows 10  (I tried two machines)

LG burner extern (I tried an intern one also)

Verbatim bdr-50 (tried another brand)

iso (tried BDMV also)

ImgBurn always sends data to the drive as quickly as possible, so any slowdowns are from the drive itself or your system being bogged down.

Lots of drives adjust the laser power as they burn and that calibration is often the reason a drive stops for a split second - which then reduces the averaged write rate.
