BUFFALO TS3430DN0802 – TeraStation 3430DN 8TB 4-Bay 2.5GbE Desktop NAS
Overview
The BUFFALO TS3430DN0802 is an 8TB TeraStation 3430DN desktop NAS configured with two 4TB NAS-grade SATA drives in a four-bay chassis. Two drive bays remain available for future storage expansion. The system is designed for centralized file storage, backup, and network data management in small and medium-sized business environments.
Technical Information
The TS3430DN0802 uses an Annapurna Labs Alpine AL-524 2.0GHz quad-core processor with 2GB of DDR4 memory and a Btrfs file system. Network connectivity includes one 2.5GbE RJ-45 port and one 1GbE RJ-45 port, while two USB 3.2 Gen 1 Type-A ports provide connectivity for supported peripherals.
The four-bay platform supports RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, and JBOD configurations. The supplied configuration contains two 4TB drives for 8TB of installed storage, while the two unused bays allow additional drives to be installed.
Compatibility
The TS3430DN0802 supports Windows 11, Windows 10, Windows Server 2022, Windows Server 2019, Windows Server 2016, macOS 12 or later, and Chrome OS. Supported network services include TCP/IP, CIFS/SMB, AFP, FTP/FTPS/SFTP, and NFS. iSCSI support is also specified for storage-network deployment.
The system uses 3.5-inch SATA NAS-grade hard drives and supports BUFFALO OP-HD2.0N, OP-HD4.0N, and OP-HD8.0N replacement drives. RAID configuration should be selected according to the required balance of capacity, redundancy, and performance.
