Good point, although if I read that properly, all of those present the data as a raw block device and therefore have to have a client-side filesystem mounted on them. Probably more sophisticated than what our intrepid adventurer was looking for

RBD as a base image for a VM is great for cloud server VMs, though!

There is no One Size Fits All solution. For you, it seems that speed is more 
important than high availability. For me, it's HA+redundancy.

Ceph has 3 ways to deliver data to remote clients:

1. As a direct ceph mount on the client. From experience, this is a pain when 
the clients hibernate.

2. As an internal ganesha NFS server running under ceph

3. As an independent ganesha NFS server using ceph as a backend.
Some deployments also do KRBD mounts onto a VM or BM system that re-exports 
them via KNFS

CephFS and RGW (with caveats) can also be exported with SMB.

RBD mounts, either through KRBD or libvirt are popular as well.
