TeraStation 3030 4-Bay NAS

The Buffalo TeraStation 3030 TS3430RN0402 is a rackmount network storage appliance with four drive bays. It ships with two 2 TB hard drives for a total of 4 TB usable capacity. An Annapurna Labs AL-524 quad-core processor at 2.0 GHz and 2 GB of DDR4 memory handle file services and RAID management. The unit includes a rail kit for standard rack installation.

Network connectivity and expansion

Two Ethernet ports provide 2.5 GbE and 1 GbE links for LAN access. Three USB ports — two USB 3.0 and one USB 2.0 — allow external storage or printer sharing. The device supports RAID 0, 1, 5, 6, 10 and JBOD for data protection or capacity aggregation. Buyers who need more than two native network ports or built-in 10 GbE should consider other platforms.

Four-bay SATA capacity

The chassis accepts four SATA drives, and only two bays are populated at delivery. This leaves two empty bays for future expansion or for configuring higher RAID levels that require additional drives. If your deployment requires all four bays filled immediately, you must purchase extra drives separately.

Questions about this item

How do I verify the NAS is operating correctly after connecting it to the network?

The front panel LEDs for Power, HDD activity, and LAN (10/100) will illuminate to show the system is powered, drives are active, and network links are established.

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

The package includes the TeraStation, railkit, quick setup guide, AC cable, warranty statement, and two 2TB drives pre-installed; additional OP-HD2.0N compatible drives are sold separately to fill the remaining two bays.

Should I choose the 4TB model or a larger capacity for my RAID 5 array?

This model provides 4TB total (2 x 2TB) and supports RAID 5 across all four bays; adding two more OP-HD2.0N drives expands usable capacity while keeping single-drive redundancy.
