Buffer Memory in DVD-ROM drives

Does the buffer memory in DVD-ROM drives play an important role and if yes could you give an example why. And secondly which DVD-ROM drive do you recommend me? I can’t choose between Asus DVD-E616 and Plextor PX-116A. I have only those two in mind because as I know they can read both the DVD-R and the DVD+R format. :confused:

No it doesn’t make any difference to my knowledge. I can recommend the Toshiba drives myself but please ask your questions in one thread instead of making several ones.
