@lorimeyers I bought a drum of 100 blank DVDs (also in a sale!). At 4.7 GB per disc for storage they can hold a lot. Essentially I burn stuff on there, write on each what it holds and put it in another (empty) drum, until it's full.
As long as you keep the discs at the same temperature/relative humidity (same place as much as possible) and keep the light out (make sure the paper wrap is still on the drum, or make another one) they'll last a long time.
