A better presentation would be to have someone make the best performance/price on AWS EC2, then someone else make the best performance/price on Hetzner and compare.
I myself used EC2 instances with locally attached NVMe drives with (mdadm) RAID-0 on BTRFS that was quite fast. It was for a CI/CD pipeline so only the config and the most recent build data needed to be kept. Either BTRFS or the CI/CD database (PostgreSQL I think) would eventually get corrupted and I'd run a rebuild script a few times a year.
