said by dave:Building a file server that keeps its files on a NAS drive seems a little indirect: the so-called 'NAS drive' is a file server (at least if it implements file protocols like SMB and NFS rather than block protocols). So with that scheme you have two network hops from client to file.
When I said NAS drive I litterally meant a drive that made for a NAS, like the WD reds or the Seagate NAS models.
