Hello. I replaced my old NEC DVD+RW 1100A For a pioneer 109 it works swell. I was going to sell it (nec 1100a) to a friend but I have read using 1 burner to read and write can be hard on it? I do not have an ebay account where I am selling dvdr's or any thing maybe burning 1 to 5 movies a week. Is this light enough or should I install the other one and use 1 to read and the other to burn?
