I don't get it -- AWS deep archive is $12/TB/yr and provides actual durability and connectivity, not just drive-in-a-shoebox. That seems pretty hard to beat by buying raw storage at retail
AWS connectivity is stupidly expensive in the outgoing direction, so that connectivity may or may not be worth much of anything. Connectivity is also a risk.
Overall glacier is only really suited for backups, and I don't need that much durability for a single backup. And even if durability is a big deal, I can get there cheaper. Especially using a realistic expected life cycle and not the warranty period.
