Buffalo TeraStation 3420DN 8TB 4HDD 4-Bay NAS Server

Buffalo’s TeraStation 3420DN is a high-performance, cost-effective 4-bay Network Attached Storage (NAS) solution, ideal for small businesses and demanding small office and home office (SOHO) users. With a powerful Annapurna Labs Alpine AL-214 1.4 GHz quad-core processor, it provides speedy transfer rates and stable operation during heavy-load work tasks. The robust central processing unit (CPU) and 1 GB of DDR3 RAM mean it can run multiple services simultaneously. This allows businesses to focus on concurrent tasks with minimal performance degradation.

Rsynch Feature

Users can make backup copies from TeraStation to a Rsync-compatible device from another manufacturer. This function also allows backups to be made from another manufacturer’s Rsync-compatible NAS to the TeraStation NAS.

Active Directory

TeraStation functions as a client of an Active Directory domain, so that domain users and groups can be used. This means that they can be used in domain environments of companies with up to 10,000 users and groups.


Buffalo’s TeraStation Series features B-Sync, which allows users to easily synchronize files between their TeraStation and 3rd party cloud services to make backups. The Buffalo NAS supports Amazon S3 Cloud Services, Dropbox, OneDrive, and Azure.

Intuitive Web Management Interface

The web interface has a dashboard that offers the user more effective views of system status, the ability to resize windows (even on the phone), and a more comfortable button layout.

iSCSI Target Support

Works simultaneously as NAS and iSCSI target.

Equipped with Reliable NAS HDDs

This series is completely equipped with special NAS hard drives – for even more performance and reliability in RAID and continuous operation.

Replication with TeraStation

By replication, a folder in two separate TeraStations is synchronized almost in real-time. This only happens in one direction (not bi-directional) – from the source to the destination. This function can be set up in LAN and WAN. WAN setup includes remote connection via port forwarding and VPN setup.

Allocation of Disk Quota

Hard disk quotas prevent the misuse of storage space by allocating appropriate amounts of storage to users.

NovaStor Backup

Including 11 licenses NovaBACKUP Buffalo Edition software. NovaBACKUP provides small and medium-sized companies that value the protection of their digital data with a complete data security solution in one package.
