Would be cool to understand the tradeoffs of the various block storage implementations.

I'm using seaweedfs for a single-machine S3 compatible storage, and it works great. Though I'm missing out on a lot of administrative nice-to-haves (like, easy access controls and a good understanding of capacity vs usage, error rates and so on... this could be a pebcak issue though).

Ceph I have also used and seems to care a lot more about being distributed. If you have less than 4 hosts for storage it feels like it scoffs at you when setting up. I was also unable to get it to perform amazingly, though to be fair I was doing it via K8S/Rook atop the Flannel CNI, which is an easy to use CNI for toy deployments, not performance critical systems - so that could be my bad. I would trust a ceph deployment with data integrity though, it just gives me that feel of "whomever worked on this, really understood distributed systems".. but, I can't put that feeling into any concrete data.
