Target burn speed 48X vs. actual around 18X?

[BJBBJB]

I have finally gotten a nice new Plextor 760A burner installed and

burned a few CDR's.

 

I have read several posts about burn speeds but I am not trying to get into the technical discussion, I am just wondering what (the way EZMC calcs it) a typical burn speed should be for a drive like this.

 

I did a CD copy and copied a 500MB file and both burns were on Verbatim 52X media. The target speed said 48X and the actual came in around 17X....

 

Are there settings somewhere that help, is this how it calculates it, or is this slow for a drive like this??

One burn was disc-to-disc. The other was from hard drive to the burner. I will check tonight if I see the burn speed pop up near the end, perhaps burn a full data disc.

 

My old burner was so slow I really have no reference point here other than the numbers on the screen.

At the theoretical limit of how fast a disc can be spun, the beginning burn speed will be somewhere around 16X, as was stated above. Depending on your drive, the speed may increase smoothly, or in "jumps". You should be able to see that as you watch a full disc burn. But you'll definitely want to do the test from your HD to take out any affect of the disc read speed.

The actual burn speed is dynamic - that is, it starts slowly and gets higher the further into the burn it goes.

 

If you have a full 700 MB of files to burn, it won't hit 48x until the end

 

This is down to drive makers quoting the speed at the fastest end of a burn so everyone expects that is the speed they will get throughout - unfortunately it doesn't happen that way

To add to what gi7omy has said. If you were copying from a other drive with it reading a CD? This could slow any burn speed down.
