My question was more about just how many TBs and ingress/egress was making AWS S3 cost prohibitive -- Wasabi's sticker price is $5.99/month (so 6x glacier but ~0.2x regular S3), and I know that Hetzner will give you a storage box that is 1TB for 9.40EUR (but the kicker there is that 10TB of traffic is included which is amazing), and there are no API/operation fees when you run your own Minio (or just use FTP/all the other built-in access methods).

Network is one thing but what am I missing here? Maybe I just think $10/month is reasonable for 1TB (because I don't have enough TBs? or use remote storage enough?), and that's different from most people who are interested in this.
