Quantum / Fireball lol
USB memory stick or external drive
01 and 10 are better for data security, but that comes at a price.
Well DVD would be the easiest but it wouldn't neccesarily last all that long. Tape perhaps, or HDD <- put that away in a good place with the right humidity and it's gonna last quite a long time.

If the drive doesn't get that many work hours it is gonna last quite a long ass time. I have a Conner CFS210A drive, it's like210mb and goes along quite happilly. Has moderate work hours.
I also have a WDAC22100 which has a lot of work hours but works fine. One thing with them tho, drives don't like power cycles a lot, it can cause them to break earlier.
