This is true, samba does in fact support hard links but it is really just like another NFS!  the filesystem on the other end of the cifs share must support hardlinks as samba is just the layer translating over the network.  Samba can scale better than NFS also.

I don't know if samba support hardlinks on "smb" shares or just "cifs" shares, I have not checked that out.  "cifs" is essential a newer version of "smb" and I don't know what the feature differences are.

I believe Samba actually does support hardlinks, but it's not a
filesystem. If you have a drive that is formatted as FAT32 for
instance, you won't get hardlinks, since FAT32 doesn't support
hardlinks. If your NAS supports NFS mounts, try that. People here
generally suggest to choose a local/external drive over a NAS: less
hassle and better performance.

Sure.
