Yeah, it's really too bad someone hasn't made a reasonably-priced archival format that consumers and small businesses can use, because LTO isn't it. The closest they have is MDISC, but the storage capacity is small, and from what I'm reading, discs advertised with this aren't necessarily all that long-lived anyway (if they're using dye).
What we need is a cheap, write-once format that can hold at least 1TB, similar to how we used to use CD-Rs 20-25 years ago, but without organic dye like those discs and with a far longer shelf life.
