Storage is a fixed fee (space on a hard drive). It make money every month when it sits there and is used.

Bandwidth costs can seem like a lot more, but when you purchase a 10 gig fibre, you have unlimited data, up until the full speed of the 10 gig fibre, 24/7. That number in TB can be calculated.

Clouds massively mark up services. Ones that underprice can have the opposite problem.

I have heard good things about the Backblaze service itself, and appreciate the hard drive reviews they put out.
