Buffalo Technology TS3430DN0804 8TB 4-Bay NAS

Purpose-built 4-bay NAS for small teams

The Buffalo TeraStation 3030 TS3430DN0804 ships with four 2 TB drives pre-configured for 8 TB total capacity and runs on an Annapurna Labs AL-524 quad-core processor at 2.0 GHz with 2 GB DDR4 memory. It targets small offices or workgroups that need centralised file storage, backup targets or media serving without a dedicated server room. Buyers who require 10 GbE connectivity, expansion bays beyond four or pre-installed SSD caching should look elsewhere.

Sustained throughput with dual Ethernet

The 2.5 GbE and 1 GbE RJ-45 ports allow link aggregation or separate traffic lanes so RAID 5 or RAID 6 rebuilds and large sequential transfers can continue without saturating a single gigabit link. The AL-524 processor maintains parity calculations during prolonged write workloads while the 33.88 W typical draw keeps heat output modest in a closed cabinet. Environments that demand sustained multi-client 4K video editing streams or database-level IOPS will exceed the platform’s CPU and memory headroom.

Tool-less drive trays and front-panel lock

Each of the four bays uses a tool-less tray that accepts 3.5-inch SATA drives; the included OP-HD2.0N drives slide in and lock with a key-operated front panel. USB 3.0 ports on the rear simplify one-off backups or printer sharing without opening the chassis. Installers who skip the RAID initialisation wizard or mix drive capacities often encounter degraded arrays that require manual recovery via the web UI.
