Re: Lowest-cost archive medium
I would love to have even something of an LTO-6 level of capacity, but at consumer prices (which they're decidely NOT--an LTO-6 drive runs nearly $6,000). Having something that can several TB of things pretty safe for the mid-term, say around five to seven years, would be really nice for packrats such as myself. Right now, external hard drives remain the most affordable choice in the consumer market, but I still have to wonder about their reliability and data retention at these lengths of time.
"Not to mention that if you really want to "archive" something for a prolonged period of time and have it readable by future generations, you're still better off sticking to ink on paper."
Kind of hard to put a movie on pen and paper. Same for a selection of music (sheet music is basically musical source code--most people prefer finished products).
