Every major storage medium has a flaw in it.
Hard Drives are known to fail randomly. Also it would be ridiculous to have a 1TB hard drive for only 1MB of data.[/li][/list]
No they don't. They only seem to fail randomly because of confirmation bias (vocal minority crying they lost their data)
You just said they fail randomly!
Flash Drives are a nightmare when it comes to reliability.
only if you buy some shitty chinese 8 GB flash drive for $4.
Sandisk Cruzer Pop 8GB failed on me 1 week after I bought it.
Paper wallets are perfect, but many power users don't have a printer since it is becoming an outdated device. Also some printers may "save" the data printed making it unsafe.
wait what? why wouldn't you have a printer? you can get a back and white laser printer for under $100.
InkJet printers are awful because you either print every day or your ink dries up. Having a LaserJet printer in your house causes lung cancer.
