A NAS (Networked Attached Storage) is a device serving files via the network. One protocol to accomplish this is NFS. So a NAS can use the NFS protocol (or another protocol).
So a Linux server providing NFS exports is, in effect, a NAS device.
Is there a good reason to pick a NAS filer over just running NFS on servers?
The appliance has the advantage of being pre-packaged and ready out of the box and probably has a web gui to make changes a little more admin friendly. A disadvantage to the appliance is that recovery of the data could be more difficult, if you get in that spot, as the underlying filesystem could be proprietary.
