Why Samba? That is not used unless you must support windows. NFS would probably better option for Linux, *inx and Mac.

I didn't know about that. I don't use windows at all, but have a Synology with a bunch of drives and use it with SMB for my multiple Macs and apple devices, haven't had any larger issues and things seem to work fine. Should I be switching to NFS ?

Samba is used for Windows support.
