DVD Burner Question....

Thread Starter 
I was wondering if there is any software for notebook DVD Burners that would force the Burner to write at full 8X write speed instead of moving up to 8X. DOES HDD RPM Speed matter in DVD Burner performance say writing to and from??? Do External DVD Burners write at full speed or do they take longer due to USB2.0 480Mbs interface???

The HDD speed of course matters as normally you read the data from the HDD.
The 4200 RPM hard drive might limit you if the drive is fragmented or you try to burn at 16X. It should be able to feed the burner with data at 8X, it works for me.
I used both external and internal burners (USB 2.0) the USB2.0 is fast enough for burning so I did not experience noticeable difference between the internal and external drives in burning time.
On the other hand the USB external drive had problems with some burning softwares.
Randomly I got errors unless I used the Nero dirver which as far as I know more tolerant so works flawlessly.
I think I usually burned a disc in 9-10 minutes with 8X speed but I will confirm this tomorrow.
Hope it helps.

It's physics -- angular velocity is variable.

As in.. the inside of a rotating disk travels slower than the outside

The writing only speeds up to 8x as the head approaches the outside edge of the disk.

Drivers are what control the speed of the burner as it burns. DVD (and CD burners) burners rarely ever burt at full speed all the way through. Usually the speed of the "burn" is variable through depending at what position the head is along the DVD.

Always make sure you have the latest drivers.
