They'll all work the same. The media may outlive the technology support. For example, how many Beta tape readers are there? How many 8" floppy readers?
Whatever you choose, if you really want the data accessible in 20 years, use hardcopy (paper) in fireproof storage.
Hard drives are prone to fail over time, CDs and DVDs can be easily scratched, so I guess that leaves USB flash drives as the most reliable electronic storage medium. They almost never fail because they rely on steady-state technology, as opposed to mechanical parts.
usb flash drives are (nearly) indestructable... i dropped mine off the roof (Don't ask why please) and there wasnt even a scratch on it.
hard drive
Probably online storage if you can afford if. it's not too expensive and as long as the company stays afloat, you should be fine
I would have to say hard drives in RAID mode would be the most reliable. RAID mode basically copies the same data across multiple hard drives, so if one fails, the data is still saved on the others.
Can you download Yahoo to a flash drive instead of HD?
