How to know my advertised rive speeds for CDs, DVDs and RWsdrive

[perfection]

I would like to know what are the readand write speeds for cds and dvds on my optical drive. Is there a dianosis tool that will give me this informstion?

i tried using nero info tool but itonly tells me the Cd write and read speeds (not for DVDs). I do not have the box of the drive so how can i have this information?

Use CD/DVD SPEED, it should tell you the model of your dvd burner.

Download the nerocdspeed 4.7.7.16 version. Then unzip it and double click on the icon for that program. It should at least give you the brand/model of your dvd burner. Are you sure your dvd rw is a burner or just a dvd-rom (reader)?
