Talking about reliability, a coupe of years ago I was tasked to put the students thesis online. Prior 2000, they were archived on 3.5" floppies, and the on CD. I was surprised to find out that a greater percentage of the floppies where readable when compared to CD (even those not older than 5 years).
Floppies were of reputable brand, while CD were on the cheap side. In both case, I tried to use the best or newest peripheral. CD and floppies had been stored in the same box, so storage was not the issue.
