Is your NAS mounted in etc/fstab? And is it NFS or SMB/Windows? If it's NFS there are mount options you can use to help you in this situation.

To answer this specific question, yes - there is a timeout associated with any network drive. Unfortunately this timeout is quite large and your terminal will hang until it times out.
