How to install BUFFALO TeraStation 3420

Getting started with the BUFFALO TeraStation 3420 is straightforward, and you can have a secure, shareable storage solution up and running quickly. Follow these steps to set up your 4-bay NAS with 16TB of included drives:

1) Position and power up: Place the rackmount NAS in your equipment rack or designated space. Connect the unit to your network switch or router using an Ethernet cable, and plug the power cord into a grounded power source. Power on the device to begin initialization.

2) Access the management interface: From a connected computer, open a web browser and enter the TeraStation’s default IP address or hostname (the device will guide you to the initial setup page). Log in with the default administrator credentials provided by Buffalo’s setup wizard.

3) Initialize drives and configure RAID: Use the web-based setup wizard to confirm the pre-installed drives, then choose a RAID configuration that fits your protection and capacity goals (for example, RAID 0 for maximum capacity or RAID 1/5/6 for redundancy). The wizard will guide you through formatting and creating storage volumes.

4) Create shares and user access: Define shared folders and assign access permissions for team members. Create user accounts and group policies to control who can read, write, or administer each share. Enable SMB for cross-platform access and ensure appropriate firewall and network settings are in place.

5) Enable backups and security features: Set up scheduled backups to protect critical data, enable encryption if desired, and configure alert notifications to stay informed about drive health or network issues. Test access from client devices to confirm smooth file transfers and permissions.

6) Connect clients and expand as needed: Map network drives on Windows or macOS clients to the shared folders, install Buffalo’s management tools if needed, and begin collaborating. If you outgrow the 16TB baseline, you can expand storage by adding more drives or adjusting RAID settings to accommodate additional capacity and performance requirements.

With these steps complete, the BUFFALO TeraStation 3420 provides reliable, centralized storage that teams can rely on for day-to-day file sharing, backups, and collaborative workflows. The intuitive interface minimizes the learning curve, while the 4-bay design offers future-proofing through RAID configurations and hot-swappable drives. This makes the TeraStation 3420 an excellent choice for small to mid-sized businesses seeking a ready-to-use, rack-mounted NAS with included drives and enterprise-grade storage features.

Great Dividers
Size: 6 Panel-120"W, Color: Beige
Love these!! Many uses. Simple, nice looking, sturdy overall. Well made. Bought to divide the unsightly storage area from the calm rest area in the basement. Also, these worked well for our garage party where the dividers let light and air in, though blocked the view of our party area from the cars driving by.

Just what I needed
Size: 4 Panel-136"W, Color: Black
I have a one bedroom apt and my son stays with me half the time. He has an air mattress in the living room until I can afford a 2 bedroom. But he’s in his early teens and needs privacy. I bought this after looking online at may of these. I’m so glad I went with this one. It covers his air mattress 3/4 of the way around and now he has his own little nook. I also gave him some led lamps and he might it like his own little nightclub. He LOVES it. And now he’s excited to be in his space. The quality is so good and there’s no see through, no gaps, it’s perfect.

Instructions could be clearer, but assembles well and is sturdy
Size: 3 Panel-102"W, Color: Black
The only reason for the lack of a star is the iffy instructions. There are a few different washers and the instructions could make the difference a LOT easier to understand and thereby reduce the need to re-do things. Other than that, the panels were easy to assemble and the parts fit well together. I was able to disassemble the screens and store them for a future use, which is nice. One caution - the feet that make the panels stand up will likely be a trip hazard, so be sure to plan the location for this device carefully.

Awesome product!!!
Size: 3 Panel-102"W, Color: Beige, Size: 3 Panel-102"W, Color: Beige
This thing is really awesome. I actually bought 2 of them and made myself a nice little enclosure to keep out any peeping Toms while I’m trying to work on my summer tan. What I was looking for is FULL privacy and this DEFINITELY provides that. Fabric is completely opaque, you cannot see anything through it which is exactly what I needed. Another huge bonus is the strips of fabric to cover the spaces in between the panels, giving TRUE privacy. This is a really well-made product, great design, great structure, and pretty easy to put together overall. The only downside is that with strong gusts of wind, it wants to tip over so as you can see I secured the bottom feet with a couple bricks to make it stable and that did the trick. But to me that is a minor inconvenience given all its other great aspects. So many other privacy dividers were still see-through… totally defeating the purpose. But this one is absolutely full privacy and PERFECT for what I needed it for!!!
