Connecting a NAS drive directly via Gigabit LAN

    OK, today I was given a 320gb Buffalo Linkstation which I would like to use for archiving DV video projects. It's a network drive of course, and although it has a gigabit lan port on it, all of our Macs are on Airport G or N. It would therefore be to slow moving the projects over to the Linkstation (connected to the router) via airport. So my question is, would it be possible to connect the Linkstation to my Mac via gigabit lan directly. It isn't important for other machines to access it, I just need to move large files quickly to, whilst remaining on our wireless network for usual internet/email. Is this possible? If so, any pointers. Would the gigabit lan be fast enough or is it better to get the drive out and put it into an enclosure? Thanks for any help you can give.

    Short answer: Yes. Long answer: maybe

    The short answer is: yes. This should be possible. Macs have the ability to create so-called "one-wire" networks. Just connect any garden-variety ethernet cable from your NAS to your Mac and they will be mostly connected. If throughput is important, get a high-quality Category 6 (Cat6) cable, and don't make it longer than necessary.

    Now for the "maybe" part. Since your two devices will be the only two things on the network, neither one will get an IP address assigned by something else in the network. Normally, your Mac or your NAS probably boots up and just makes a request into the network for a DHCP address. Something in your network (the router, most likely) assigns one. Your NAS and your Mac, however, probably act differently when nobody's out there to assign an address.

    Your Mac will pick one from a special range of IP addresses. It will be 169.254.XXX.XXX. (Where the XXX.XXX part is just randomly picked). Your NAS may or may not do that. To make this work, you'll have to do one of two things: either change your Mac's IP address to be in the same network range as your NAS, or change the NAS's IP address to be in the same network as your Mac. Since I know MacOS and I don't know your NAS, I'll tell you what to do for the Mac.

    Go into Settings, Network, and select your ethernet adapter. You should see a warning that you have a self-assigned IP address. That's normal. You need to know what IP setting your NAS uses. Once you know that, go into the network settings on your mac and tell it to configure the IPv4 address "manually" (it will say "DHCP" to start with). Then enter the numbers very similar (but not the same) as what your NAS uses. My recommendation: take the NAS's IP address and just add 1. If it's, set your Mac to be Keep the netmask and everything else the same.

    Without getting into how TCP/IP settings really work, that's the quickest advice I can give you. The main thing to know is that Macs automatically configure themselves for one-wire networks, and all you have to do is get compatible IP addresses to make a connection. I do this between my MacBook Pro and my old G4 tower all the time to get gigabit connectivity and do file transfers.

    To connect your NAS to Mac directly on OS X 10.10 or later, follow these steps:

    1. Launch [Sharing] in [System Preferences].
    2. Set [Share your connection from] to [Wi-Fi] which is the configuration name for 802.11n device.
    3. Set [To computer using] to [Ethernet] which is for Gigabit Ethernet device.
    4. Click on [Internet Sharing] to enable.

    Then use vi to look for “OFFER sent + NAS host name” in /var/log/system.log to get the IP of NAS.

    For QNAP devices, launch Qfinder before turning on NAS. It will show up in the list with IP address. If you turn on NAS before launching Qfinder , it won’t be able to find it.

    For Synology devices, Synology Assistant won’t help.

    Wish it helps!

    Does the Buffalo device have a USB 3 port that might be used to connect directly to the Mac? If so, that would be much faster than ethernet.

    7 year old thread. OP hasn't been logged in here in 4.5 years. I'm going to guess that the OP's device didn't have USB3 since the post was before USB3 was released.

    I know it is an old thread but it comes up in the first page in google search. That's why I leave my solution here to help those who found this thread.

    About USB 3.0 and Gigabit Ethernet, I agree USB 3.0 is much faster and easier to use. I choose NAS for other consideration: power and fan.

    Most of the USB 3.0 external storage box doesn't comes with fan. I am worry the heat after normal daily usage.

    About power, I found most external storage box comes with a less current adapter. I doubt if it may support start current steady after long use. That's why I write Match Hard Disk Startup Current with Power Adapter Output Current to explain the important of power adapter.

    Wish it helps!

    Best regards,
