It’s a) a mixed calculation. Not everyone is using the 1TB and the Transfer. b) Storage at scale is cheap. c) Transfer is even cheaper at scale. d) It’s “only” on one Server with a raid system e.g. no cloud with multiple copy’s.
Because that's what it costs when you're not maximizing shareholder profits or paying silicon valley wages.
Storage is cheap. I personally wouldn't buy into this because a 1TB drive is only like $30 nowadays, but you do you.
I’ve tried two times (once 1 year ago and one more time one month ago) without success to register an account on Hetzner. They always end up either directly rejecting me or asking for my ID/passport. There’s simply no chance I’m giving a copy of my passport (which is not even a guarantee of admission) to such a private company. I guess I’ll stay with digital ocean.
