Just a quick update on my experience with my new drive.
I switched drives at the store today and I saw some improvements. I also read some posts here on how to setup your system to get maximum performance.
Now the drive at least outperforms my old external HP 200 dvd-writer.
But still the Memory buffer seems to be the major problem. Sorry if Im seem a bit thick here but I can't shake the feeling something is not right.
Below are two graphs of an actual burning. I used Alcohol 120% to burn a img-file.
The first one show burn speed measured every 0.5 seconds(purple graph) and a sampling every 4 second(turquoise). As is painfully clear it drops to about 1.6x at 3.2GB burnt.
The second one is CPU(green) and memorybuffer(purple) utilisation.
A few spikes in CPU usage is not an issue but at 42% the memory buffer just bottoms out.
I have read on the forums that the buffer goes up and down alot but the memorybuffer remains empty. And after a while burn-speed goes down most likely due to burnproof technology.
Is this to be expected or am I doing something wrong?
