About how many burn hours can you expect to get out of a plextor 760a?
What's considered high usage as far as the life of the drive is concerened?
I have burned about 300 DVDs with mine. About 75 dual layers. Burned most of them at 4x. The rest single layers mostly at 16x speed. No problems so far. I would expect that it will do maybe 10 times more burns. But its just a guess.
I’m trying to guage the cost of a used drive vs how much life might be left in it.
That is actually a difficult thing to balance. Most users selling their drives sell it either because they didn’t use it much or because it has been used so much that it starts malfunctioning
