4-Bay Desktop NAS for Small Teams

The Buffalo TeraStation 3030 TS3430DN0802 delivers an 8TB RAID-ready appliance with a quad-core AL-524 processor at 2.0GHz and 2GB DDR4 memory. It targets small businesses or advanced home users who need centralised file storage, backup targets and shared media access without managing a full server operating system. Dual Ethernet ports at 2.5GbE and 1GbE plus two USB 3.0 ports provide flexible connectivity for clients and expansion drives.

Replaces Single-Drive or USB-Attached Storage

Moving from a single external drive or basic USB NAS removes the single point of failure and adds RAID 0, 1, 5, 6, 10 and JBOD options for redundancy or performance. The jump is worth it when uptime matters, when multiple users access large files simultaneously or when scheduled backups need more throughput than a single 1GbE link can sustain. The included 2×4TB drives populate half the bays, leaving room to grow capacity later.

Tool-Free Drive Installation with Standard SATA

Four hot-swap bays accept compatible SATA drives using the supplied front-panel key; no screws or trays are required beyond the drive carriers. The unit powers from 100-240 VAC and draws 33.88W under typical load. Common issues arise when mixing drives of different firmware revisions in RAID sets or when the 2GB memory limit restricts concurrent service counts; plan drive purchases and service workloads accordingly.

Questions about this item

What drive size and interface do the four bays accept?

The four bays take 3.5-inch SATA drives; the unit ships with two 4TB drives and supports OP-HD4.0N models.

How do I get the NAS onto the network for the first time?

Connect the included Cat 5e cable to the 2.5GbE or 1GbE port, power on, then run the web setup wizard; the step often missed is setting a static IP before joining a domain.

Which components can be replaced later and how?

Drives are hot-swappable via the front trays; the 2GB DDR4 memory is soldered and not user-replaceable; the power supply is internal and requires disassembly.
