I have two problems with the data as provided. First, the advantage Glacier has over a NAS is that it's offsite. If my house goes up in flames, Glacier is fine, but my NAS may be toast. I also don't think factoring in resale value is a completely fair argument since there are lots of things that can't be accounted for in resale, and it's more a snapshot of current resale value than that of a few years from now. Glacier may be slow to retrieve and have penalties for early retrieval, but that's a small cost to pay (I think) if I have a catastrophe and need my data back.
