4-Bay Desktop NAS with 4TB Storage

The Buffalo TeraStation 3030 TS3430DN0402 is a desktop network-attached storage unit with four drive bays. It arrives populated with two 2TB drives for a total of 4TB raw capacity. An Annapurna Labs AL-524 quad-core processor at 2.0GHz and 2GB DDR4 memory handle file services and RAID management.

Suitable Uses and Limits

This unit suits small offices or home users needing centralized file storage with hardware RAID 0, 1, 5, 6, 10 and JBOD options. The dual Ethernet ports provide link aggregation or failover. Buyers needing more than four bays, 10GbE connectivity, or expandable memory beyond the soldered 2GB should consider other platforms.

Deciding Specification — Dual 2.5GbE and 1GbE Ports

The network interface combines one 2.5GbE RJ-45 port and one 1GbE RJ-45 port. This specific mix determines whether the NAS can saturate a 2.5Gbps switch uplink while maintaining a separate management or backup path. Verify your switch and cabling support 2.5GbE to use the full bandwidth.

Questions sur cet article

How can I verify the TS3430DN0402 is operating correctly after initial setup?

Check that the Power LED stays solid, the HDD LEDs show activity on both installed 2TB drives, and the LAN LED lights for the 2.5GbE or 1GbE port you connected; then log into the web UI to confirm RAID status reads healthy and the 4TB volume is mounted.

What ships with the unit and what must I purchase separately?

The box contains the TeraStation 3030, quick setup guide, Cat5e Ethernet cable, AC power cable, front panel key and warranty statement; extra SATA drives beyond the two pre-installed 2TB units are not included and must be bought separately.

Which capacity version of the TeraStation 3030 should I choose for a small office needing redundancy?

This TS3430DN0402 model comes with 4TB as 2 x 2TB drives, leaving two empty bays so you can add matching drives later to grow a RAID 5 or RAID 6 array without replacing the existing pair.
