NEC ND-2500A or Pioneer AO7

Which burner should I buy? The NEC ND-2500A or the Pioneer AO7. I will mainly be using it for data storage and I may try to backup a few of my DVD’s. I will also be burning game images to my hard drive so that I can play them without disks.

Should this have been posted in a different area of the forums?

i think all dvd writer are crap and the disk are just as bad ,there a long way to go befor some one bring one out that work ok
