Don't forget B2 involves putting that data onto multiple hard-drives and ensuring it isn't lost. What if that single disk were to be lost? You're paying Backblaze to ensure that GB can be accessed in the future
This was a cost analysis, mostly for those that can't afford B2. You can buy two drives for the cost of a year at Backblaze and have N+1 redundancy.

No doubt, which is why I prefaced this with "If you don't need to have your data in the cloud".
