Dropbox is $10/TB/mo, which is the "old" industry standard (and still what most big guys charge). Backblaze is $5, but they charge egress fees, so usage matters. Dropbox doesn't charge for egress, but there are limits on "Public" folder bandwidth (and you can't pay for more if you max out). I don't think there are limits on private content, but I bet there's a soft throttle or some limit that will get you contacted.

There aren't a lot of options for <$5/TB and they all charge egress. I've tried Backblaze, pCloud, and DO Spaces. My specific use case is storing full HD movies for streaming via Plex, which requires a fairly reliable 6Gbit/second, and most of them can't keep up. DO Spaces did the best of all the ones I tried, so I'm using that for now, but it's just skating the edge of usability.

For $6 per month (paid yearly) you get 1tb of OneDrive + office (desktop applications). My math maybe off but if you buy office every 3 years for $200 then you're already even.... And 1TB of storage is just free really.

I should add that places like Backblaze and pCloud and DO Spaces and others charge per GB stored, so if you're using 1.3TB it's prorated accordingly.

0. You can only get 2 TB+
