NAS offers safe concurent access (generally, there might be some NAS devices outthere that do not). NAS device will manage file system internally, and export it over NFS or SMB protocols to the clients. It's going to be slower and less efficient than SAN device though (because of the upper protocol overhead), and the set of features offered by file system might not be what would be available if file system was managed by client's operating system itself.

Or, in the case of a smart NAS and a dumb client you might have better features like frozen snapshots and remote mirroring - and without worrying about client software issues corrupting the filesystem.
