DVD burning on nMP

Hello

hi, what are the ways to have a fast burner for the nMP ?
Since most of the smaller USB DVD burners are USB2, the speed will be quite slow. I saw some USB3 Dvd burners on eBay, are they any faster ?

someone, please, correct me if i'm wrong. but a dvd recorder recording at 24x is roughly 265 Mbit/s and USB 2.0 is rated at 480 Mbit/s so using USB 2.0 versus 3.0 should essentially be moot as the drive wouldn't be able to saturate the line anyways. read speeds may be a different story (like 48x) but if you doubled the 24x speed (530 Mbit/s) it would only be just above max throughput. to me, it wouldn't warrant the price increase (if there is one) for a USB 3 drive.

Hi Rueyloon. There are also USB 3 DVD burners on Amazon and OWC also offers a burner with USB 3. I was told that it's better to burn DVDs at medium speed and avoid using the maximum. This is to ensure the quality of the discs in storing the file specially with video files. In using faster speeds, there might be some risks on errors. http://superuser.com/questions/1986...cd-slower-help-assure-it-will-not-have-errors

If you just want to read and write only DVD, then I agree with you that using a USB 2.0 interface is more than enough, especially when there is currently no DVD reader/writer that could read DVD media at 48X speed. The USB 3.0 interface is suited for reading/writing the BD media, especially above the 8X speed as explained here.
 
I deliver files on DVD to clients.

Burning with the internal DVD drive is faster, using the USB writer at times I only hit 2X, with verification, the whole process can be bit draggy.
 
My USB 2.0 Liteon external DVD writer burn disk as fast as my cMP's internal SuperDrive.

As the others said, USB 2.0 is fast enough for the fastest DVD writer. The bottleneck is the DVD writer itself, not USB 2.0
 
My clients used to want CDs and DVDs but now I've persuaded all of them to accept USB sticks or web transfers. It was a revelation to several of my clients who now insist that all their freelancers deliver content in this manner.
Unless there is an absolute business critical reason for DVDs or CDs it's well worth trying to persuade them to move into the 21st century.
