Cheap and expensive. Depending what industry you are coming from. Being in the hosting industry, anything >$1/TB seems high.
But the, if the comparison is big cloud (AWS, Azure, GCloud) that charge $70/TB+, sure $10/TB and 2TB included seems cheap.
They essentially have to compete against Digital Ocean and Linode... those are their 2 largest competitors that I can think of off the top of my head. I have experience with all 3. For the price, I prefer Linode.
