BUFFALO TS3430DN0804 – TeraStation 3430DN 8TB 4-Bay 2.5GbE NAS
Overview
The BUFFALO TS3430DN0804 is a TeraStation 3430DN desktop business NAS with 8TB of installed storage using four 2TB NAS-grade hard drives. It provides four drive bays, 2.5GbE and 1GbE network connectivity, 2GB of DDR4 memory, software RAID, and business-oriented network storage features.
The TS3430DN0804 is shipped with RAID 6 configured as the factory storage mode. The four-drive design also supports RAID 0, RAID 1, RAID 5, RAID 10, and JBOD/Individual Disks for deployments requiring different combinations of capacity, redundancy, or performance.
Technical Information
The system 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 interfaces support the installed NAS-grade hard drives.
Network connectivity consists of one 2.5GBASE-T RJ-45 port and one 1GbE RJ-45 port. The 2.5GbE interface supports 2.5Gbps, 1000Mbps, 100Mbps, and 10Mbps operation, while the additional Gigabit interface provides a separate 1000/100/10Mbps network connection.
Two USB 3.2 Gen 1 Type-A ports provide peripheral connectivity at transfer rates up to 5Gbps. Buffalo also provides abnormal login and file activity detection and remote access/configuration capabilities on the TeraStation 3430DN platform.
Compatibility
The TS3430DN0804 supports TCP/IP networking and network file services including SMB/CIFS, AFP, FTP, FTPS, SFTP, NFS, and HTTP/HTTPS. The platform also supports SNMP and iSCSI target functionality for compatible storage environments.
Client operating systems listed by Buffalo include Windows 11, Windows 10, Windows Server 2022, Windows Server 2019, Windows Server 2016, macOS 12 or later, and Chrome OS. The 2.5GbE port supports IEEE 802.3bz, while the network interfaces also support established Gigabit and Fast Ethernet standards.

DC Supplies Product Note
The TS3430DN0804 uses four installed 2TB drives and ships with RAID 6 as the factory configuration. Because RAID 6 reserves dual-drive parity, its usable capacity is lower than the raw 8TB installed capacity but provides protection against two drive failures within the array.
