Compact 2-bay NAS with dual Ethernet

The Buffalo TeraStation 3030 TS3230DN0402 is a desktop network-attached storage device pre-populated with two 2 TB drives for a total of 4 TB. An Annapurna Labs Alpine AL-524 quad-core processor at 2.0 GHz and 2 GB of DDR4 memory handle file serving and RAID management. It targets small offices and home users who need straightforward shared storage without configuring drives themselves.

Thermal and power profile

The unit draws 33.88 W under typical operation from a 100-240 VAC 50/60 Hz supply. Operating temperature range is 0°C to 40°C with 10-80 % non-condensing humidity. Two network ports — one 2.5GbE and one 1GbE — provide wired connectivity while the fanless chassis keeps acoustic output low for desk-side placement.

Bundled accessories and software impact

The package includes a quick setup guide, a Cat 5e Ethernet cable, an AC power cable and a front-panel key for drive bay access. These items let a single administrator deploy the NAS and secure the drives without sourcing extra cables or tools. RAID 0, 1 and JBOD modes are selectable during initial configuration to match redundancy or capacity priorities.

Questions about this item

How do I install the included 2TB drives into the 2-bay chassis, and what step is often missed?

Slide each 2TB drive into a bay until the SATA connector seats firmly, then lock the front panel with the supplied key — skipping the lock leaves drives loose and can break the SATA connection.

What maintenance or replacement will the TS3230DN0402 need over time?

The two 2TB drives are the only field-replaceable parts; plan to swap a drive if SMART errors appear or capacity runs out — the 2GB DDR4 memory is soldered and not upgradeable.

What limit appears first during sustained heavy writes on the 2.5GbE port?

The Annapurna Labs AL-524 quad-core processor and 2GB DDR4 become the bottleneck before the 2.5GbE link saturates, capping continuous throughput well below the port's theoretical maximum.
