I did some re-scan of the Mitsubishi(ä¸‰è±åŒ–å¦) DVD+R i burned about 3 years ago. below is the result.

Disc type: Mitsubishi 8x (ZD-3596)
Burn using: PIONEER DVR-112 (6x burn speed)
burn date: 2007-10-24
rescan date: 1010-05-03
i am sure that when the time i burn the max PIE is around 4 to 8. The PIF has unchanged.
other then this result posted, i also scanned disc i burned 6 months ago (Mitsubishi 16x burn at 8x) and the result was very bad, with max 40 PIF at the end of the data track(4000MB<) (usually less then 3).
so in my estimation, i think the old 8x disc may only survive for 10~15 years and 16x ones around 5~10 years.
so how your's result?
I think after we have a few result in this thread, maybe we can start compare and discuss on what is the best way to store and transfer the data "physically".
