Ceph shared filesystem (CephFS) is the primary way of storing data in nautilus and allows mounting same volumes from multiple PODs in parallel (ReadWriteMany).
Ceph block storage allows RBD (Rados Block Devices) to be attached to a single pod at a time (ReadWriteOnce). Provides fastest access to the data, and is preferred for smaller (below 500GB) datasets, and all datasets not needing shared access from multiple pods.
