When I moved out from my parents I took a box with aprox 100 floppies. I was pleasently surprised when only 2 were unreadeable all others were ok. The other box with CDs had a much higher "fault rate". Go figure.

CDs turned out to be terrible for long term storage, because the actual bits are pits in the very thin aluminum layer that's bonded to one side of the transparent polycarbonate disk. The back side of that aluminum often had nothing but a painted label to protect it.

DVD otoh, seems much more durable. The storage layer is sandwiched between two decent thicknesses of poly. But who knows, only time will tell.
