I really wish there was a benchmark comparing all of these + MinIO and S3. I'm in the market for a key value store, using S3 for now but eyeing moving to my own hardware in the future and having to do all the work to compare these is one of the major things making me procrastinate.
Minio gives you "only" S3 object storage. I've setup a 3-node Minio cluster for object storage on Hetzner, each server having 4x10TB, for ~50€/month each. This means 80TB usable data for ~150€/month. It can be worth it if you are trying to avoid egress fees, but if I were building a data lake or anything where the data was used mostly for internal services, I'd just stick with S3.
minio is good but you really need fast disks.
They also really don't like, when you want to change the size of your cluster setup.
No plan to add cache disks, they just say use faster disks.
I have it running, goes smoothly but not really user friendly to optimize
