I had a 12x cd-r drive back when they were popular and a multiple of what blu ray burners are today $$. Sad really, as the rate of innovation has declined with all media, hard drives included.
I don't remember if it died or I just discarded it-- I'll have to look again.. IIRC there were not many firmware updates for that drive. I know an old Memorex 2x definitely bit the dust though after like 400+ burns. Given how expensive media was -- that was an accomplishment in itself. Definitely worth it for converting analog audio tapes to CD-Audio at the time. Still have those, and still PLAY just as good :))
