CDs/DVDs/tapes could easily melt or warp rendering them useless, so I'm very hesitant to use them. I've seen more exotic solutions that let you print your digital data to paper an optically re-import it later should you ever need it, but it seems overly cumbersome and error prone should it be damaged or fire scorched. That leaves my best options being either a classic magnetic platter drive, or some sort of solid state storage, like SD cards, USB flash drives, or a small SSD. The problem is, I can't decide which would survive better if ever exposed to extreme temperatures, or water damage should my house burn down.
Most people would just suggest to store it in "the cloud", but I'm naturally averse to doing so because that means someone else is responsible for my data and I could lose it to hackers, the entity going out of business, etc. Once it leaves my home, I no longer fully control it, which is unacceptable. My thought being "they can't hack/steal what they can't physically access." What medium do other Slashdot users use to store their most important data (under say 5GB worth) in an at-home safe to protect it from fire?
