Buffalo TeraStation 3420RN 8TB 4-Bay 1U Rackmount NAS Server (4 x 2TB)

The Buffalo TS3420RN0804 is a 1U rackmount NAS server that brings 8TB of dependable, round-the-clock storage to small businesses, branch offices, and home workspaces that need a secure place for shared files and backups.

Inside the enclosure you will find four 2TB NAS-grade hard drives. You can keep them in a high-capacity JBOD arrangement or choose RAID 0, 1, 5, 6, or 10, depending on whether speed, redundancy, or a balance of both matters most to your workflow. Each drive sits in a hot-swap bay, so if one ever fails you can replace it without shutting the system down and interrupting your team.

An Annapurna Labs processor that runs at 1.4 GHz with four cores powers the unit, and 1 GB of DDR3 memory keeps everyday tasks smooth. That combination handles simultaneous file transfers, media streams, and scheduled backups without bogging down, which is ideal for design firms, architecture studios, or any office where several users touch large files all day long.

Dual Ethernet ports support up to 2.5 GbE speeds, giving you flexible options for link aggregation or network redundancy. Three USB 3.0 ports make it easy to add external drives for quick data offloads or snapshots. Active Directory integration accommodates up to 10 000 user accounts, so the NAS can slide right into an existing Windows domain without extra configuration headaches.

For off-site protection, the TeraStation syncs with popular cloud services such as Amazon S3, Dropbox, OneDrive, and Azure. Daily snapshots or versioned backups can travel straight to the cloud, keeping data available even if the physical office faces an outage or disaster.

The server is built for 24 / 7 duty and comes with a three-year warranty. Buffalo’s VIP service includes 24-hour hard-drive replacement, an assurance that busy IT staff can appreciate when uptime is critical.
