This article covers BUFFALO TeraStation 3430DN 4-Bay 8TB (4x2TB) デスクトップ スモールメディア ビジネスNAS(ハードドライブ付き).

## Overview
The BUFFALO TeraStation 3430DN is a 4-bay desktop NAS designed for small-to-medium businesses seeking a turnkey storage solution. It ships with four 2TB NAS-grade hard drives preinstalled and pre-configured in RAID 5, giving you 6TB of usable capacity out of the box. The 2.5GbE network interface allows faster file transfers than standard Gigabit Ethernet, making it suitable for workgroups of 10–30 users. Hardware encryption, two-factor authentication, and intrusion detection provide enterprise-level security without extra licensing.

## Connectivity & Compatibility
The TeraStation 3430DN includes a single 2.5 Gigabit Ethernet port for network connectivity. It supports Windows, macOS, and Linux clients, and can serve as an iSCSI target for block-level storage. Cloud sync with Dropbox, OneDrive, and S3 is built-in, enabling hybrid cloud deployments. The included rail kit allows rack-mount installation, and the unit also supports USB expansion for additional backup targets (e. g. , external drives).

## Product Info
BUFFALO backs it with a 3-year warranty and 24/7 phone support in the US, plus optional data recovery services. The box contains the NAS unit, power adapter, Ethernet cable, quick start guide, and rack-mount rails. Made in Japan and TAA compliant, it meets government procurement standards.

## Best Use Cases
Small office file server (10–30 employees): Pre-loaded drives and default RAID 5 minimize setup time; no need to purchase drives separately or configure RAID manually. Centralized backup target: Use the built-in backup software to schedule automatic backups from multiple Windows PCs and Macs; encryption protects data at rest. Hybrid cloud storage: Leverage cloud sync to keep local copies of cloud files, reducing download latency and providing offline access. Not ideal for high-performance workloads like 4K video editing or large databases that require NVMe-based NAS. For those, consider models with M.2 SSD cache or 10GbE.
