Hi all. I am curious if the following question I am going to ask makes a big difference or not. I just purchased a Combo drive from Samsung, the SM-348. I thought that I was getting the retail version of the drive but I misread and ordered the bulk version. There is no difference between the two except that the bulk version has 2 mb of memory, and the retail has 8mb. Is the memory in a burner and DVD combo that big of a deal? Is this something that I need to return to get the better one, for a more than $20 increase in price? I was reading online that the memory buffer isn't that big of a deal now that there are countless buffer underrun protections. Is this correct? Thank you for your help.
