Nero sleeping?



In the reviews of drives, times are usually compared on seconds.

The Plextor Premium needs 2:38 for an entire CD in Nero.

I’ve burned such a CD now in cdrecord:
Starting to write CD/DVD at speed 52 in real RAW/RAW96R mode for single s

Last chance to quit, starting real write 0 seconds. Operation starts.
Waiting for reader process to fill input buffer … input buffer ready.
BURN-Free is ON.

BURN-Free was never needed.

cdrecord: fifo was 1 times empty and 3323 times full, min fill was 0%.

As you can see, cdrecord needs 7 seconds less for the same job! 7 seconds, that is the difference which you get between a liteon 52x @ 48x and @ 52x…

The speed of the burning process itself is controled by the drive after the recording speed is set… so what is Nero doing during these 7 lacking seconds? It can’t be precaching that long…

I get BTW a similar result on the LiteOn 52x.


I’ve always thought Nero takes longer than others… I’m sure the Ahead people around here knows :slight_smile:


Alex, do you have the same size read buffer in each program?


the difference is a few MB, but my hard discs do more than 30 MB/s…
