Equipped with SSDs

This series is equipped with SSDs and therefore very shock / vibration resistant and extremely fast.

High transmission speed

The 10GbE connectivity impresses with exceptional speed.

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.


With this device you are supported by VMware if you have an ESX problem because this NAS device is VM-ready for NFS and iSCSI.

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.

Hot-swap function increases data security

With the hot swap function, the TeraStation™ automatically switches off the defective hard disk even if one hard disk fails, so that it can be replaced safely without interrupting work or losing data.


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.

Including Buffalo VIP service

Replacement of defective hard disks within 24 hours

If you want to replace a defective hard disk, just let us know. If your order is in the system before 12 noon and the hard drives are in stock, they will be replaced within 24 hours. Applies within the 3 year warranty for each TeraStation and LinkStation NVR sold in the EU. (Outside the EU it can take longer).

Allocation of disk quota

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

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.
