NFS, or Network File System, is a distributed file system protocol that allows you to mount remote directories on your server. *Block storage* is a generic term used to describe network-based storage volumes that are usually offered by hosting providers. Block storage usually does not provide its own API for direct access. Instead, it needs to be mounted to an existing server and shared from that server. Running an NFS server on an attached droplet is a good solution to expose block storage.
