I'm considering buying a BR reader along with the writer so that I will not wear out the writer. I always had a combo of writer-reader in my computers for this reason. The BR writer (and reader, if I get one) will be used for personal data, and once in a blue moon (or never) for a movie rip.
I guess to answer this question I need to say how much reading I expect to do with the drive. The answer is not a lot. The BR disks will be used for archiving data and that is going to be, what I consider, light use. I expect to write, at maximum, 10 (50GB or 100GB) disks in a month and to read even less. That's because HDDs will be the 'data read' medium for me, with BR disks having a supporting role as one more point of redundancy.
So to answer my own question, a BR reader is not necessary.
But before I go ahead with this decision, I would like to read your opinion --and personal experience-- on this.
After what point of using my BR writer for reading data, should I begin to consider buying a dedicated reader?
