It's a bit apples to oranges comparison. Dropbox is a consumer product, like Google Drive. Nearline is targeted to app developers and enterprises

Exactly, so why would the lower-level service aimed at big slow transfers be more expensive than a full-featured product?

There's a few reasons:

* Dropbox doesn't guarantee 11 9s like this service does - when I'm backing critical data up, I want to make sure it's _there_. * Dropbox likely wouldn't take kindly to me storing 10PB, whereas that is what this service is designed for. * I've got SLAs and guaranteed speeds with this, Dropbox isn't designed for me to suddenly download 10PB very quickly.

Where are you seeing these durability claims? I can't find them. And what would 12 9s durability even mean? You lose one byte out of every TB?

The detailed pricing is at https://cloud.google.com/storage/pricing#nearline-pricing In short, if I'm understanding correctly: $0.01 per GB per month storage $0.01 per GB retrieval Normal egress fees on top, so additional ~$0.10 per GB if you want to retrieve outside of Google Cloud. Early deletion fee. Effectively just a minimum storage charge of 1 month. It seems this is cheaper than Glacier and quite a bit simpler…

Unless Glacier just changed their pricing, how is it cheaper and simpler? Glacier is also $.01/GB storage, but only $.09/GB retrieval, which is cheaper than google's $.12/GB. Glacier also comes with 1st GB retrieval free/mo.

This is a nail in the coffin of the SaaS backup industry (Backblaze, RescuePlan, etc.). With storage becoming essentially free the last excuse for not using self-hosted, secure backup tools like Arq[1] disappears. [1] http://www.haystacksoftware.com/arq/

Backblaze is $5/mo per computer. If I have 4TB on a computer, it's still just $5/mo.

My guess would be disk drives that are otherwise used for I/O intensive purposes, and where there's tons of unused/wasted space. 4MB/s is only around 4% of the bandwidth of a modern 1TB hard disk.

You can store 1 Pb and get 4000 MB/s

Presumably distributed across 1000 times more disks.

12 9s is new to me too. Not worked on anything better than 5 9s (5 mins downtime/year), and Wikipedia only goes to 9. 9 9s comes to 35ms downtime a year. I can't think of anything that needs more than 5 9s, let alone 9.
