4-Bay Rackmount NAS with 32TB

The Buffalo TeraStation 3030 TS3430RN3204 is a new 4-bay rackmount network storage device that ships with four 8TB drives for 32TB of total capacity. It runs on an Annapurna Labs Alpine AL-524 quad-core processor at 2.0GHz with 2GB of DDR4 memory. The unit supports RAID 0, 1, 5, 6, 10 and JBOD for flexible data protection.

Small offices needing high read/write RAID

Teams that want redundant storage with hardware RAID levels and dual-speed Ethernet will find this a fit. Buyers who need more than four drive bays, 10GbE connectivity, or expandable RAM beyond the soldered 2GB should look at other models.

32TB pre-installed in RAID-ready bays

The four included 8TB SATA drives deliver 32TB raw capacity out of the box. This fixed drive set determines the starting storage ceiling before any RAID overhead is applied.

Questions about this item

What replacement drives are approved for the four SATA bays when a disk fails?

The compatibility list specifies OP-HD8.0N drives, so matching 8TB SATA units from that series are the direct replacements.

Which component limits sustained throughput first — the 2.5GbE port or the Annapurna AL-524 processor?

The single 2.5GbE RJ-45 port sets the network ceiling, while the quad-core 2.0GHz processor handles RAID 5 or 6 parity without becoming the bottleneck.

How much heat and noise should I expect from the 33.88W power draw in a 0°C – 40°C rack environment?

At 33.88W the unit runs cool enough for standard rack airflow; fan noise stays low under typical loads and the operating range covers 0°C to 40°C non-condensing.
