BUFFALO TS3430DN0402 – TeraStation 3430DN 4TB 4-Bay 2.5GbE NAS
Overview
The BUFFALO TS3430DN0402 is a TeraStation 3430DN desktop NAS configured with two 2TB NAS-grade hard drives in a four-bay chassis. The 4TB configuration is supplied with factory RAID 1, providing 2TB of usable capacity while leaving two drive bays available for future storage expansion.
Technical Information
The TS3430DN0402 uses an Annapurna Labs Alpine AL-524 2.0GHz quad-core processor with 2GB of DDR4 memory and a Btrfs file system. Its four SATA 6Gbps drive bays support RAID 0, 1, 5, 6, 10, and JBOD. The installed two-drive configuration is factory configured for RAID 1.
Network connectivity consists of one 2.5GbE RJ-45 port and one 1GbE RJ-45 port. The 2.5GbE interface supports 2.5Gbps, 1000Mbps, 100Mbps, and 10Mbps Ethernet operation. Two USB 3.2 Gen 1 Type-A ports provide up to 5Gbps connectivity for compatible external devices.
Compatibility
The TS3430DN0402 supports TCP/IP and network file services including CIFS/SMB, AFP, FTP, FTPS, SFTP, and NFS. Buffalo lists compatibility with Windows 11, Windows 10, Windows Server 2022, Windows Server 2019, Windows Server 2016, macOS 12 or later, and Chrome OS. The platform also supports iSCSI, Active Directory integration, cloud services, and remote configuration.
Key Features
- 4TB installed capacity using two 2TB NAS-grade HDDs
- Four-bay desktop chassis with two open bays
- Factory RAID 1 for two-drive data redundancy
- 2.5GbE plus 1GbE RJ-45 network connectivity
- 2GB DDR4 memory with 2.0GHz quad-core AL-524 processor
Applications
The TS3430DN0402 is suited to centralized business file storage, workstation backup, departmental file sharing, private cloud storage, and shared network data services. Its 2.5GbE interface provides higher network bandwidth than conventional Gigabit Ethernet when connected to compatible multi-gigabit infrastructure.
DC Supplies Product Note
The TS3430DN0402 combines a four-bay chassis with only two factory-installed drives. The factory RAID 1 configuration provides 2TB of usable storage from the 4TB raw capacity, while two additional bays remain available for supported drive expansion and alternative RAID configurations.
