I have found a couple of old threads on the net on this topic but I thought it might be worth asking it to get a (possibly) more up to date answer.
I am about to embark on a large CD-R burning project (approximately 300 disks at first, with a long term total of around 600 over the next few years). I have acquired two brand new Pioneer S09J-X burners for the project (one is currently a spare brand new still in the box just in case something happens to the one I have in service).
What I would like to know is if there is any way to tell how long these burners will continue to maintain their performance as time goes by and they burn more and more disks?
The last burner I bought (a much cheaper USB one) lasted around 160 CD-R burns from new, then died completely - unable to read anything at all let alone write. So it seemed to go from hero to zero in an instant.
Is this normally the case for a burner or does (can) performance gradually deteriorate from "new" specs over time? And if the latter is the case, what metrics can I use to determine the "fitness" of the burner at any given time? Is something like a Diskspeed disk quality test (using a different USB burner as the Pioneer cannot perform this test) a satisfactory way of determining if the burner is still effectively performing "as new"?
I'm just a bit worried that performance may somehow "degrade" over time (even though the produced disks can be read perfectly and don't have average error counts any worse than when the burner was new) and that burned disks so produced may have a shorter readable life as a result.
