Product Overview

Designed for professional environments, the BUFFALO TeraStation 5420DN delivers robust and scalable network-attached storage in a compact desktop form factor. Equipped with two pre-installed 16TB SATA III drives (totaling 32TB) and two additional bays for future expansion, this unit offers flexibility for businesses looking to grow their storage capacity. The storage operates in JBOD mode and supports RAID configuration capabilities (not explicitly stated), making it suitable for data-intensive applications.

The unit is powered by an Intel Atom C3338 dual-core processor running at 1.5 GHz, combined with 8 GB of DDR4 memory, ensuring stable performance for multi-user file access, data backup, and virtualization workloads. Connectivity includes a 10GbE-capable Gigabit Ethernet RJ-45 port and two USB 3.0 ports, making it ideal for quick data transfers and peripheral connections. The system runs on Microsoft Windows Storage Server 2016, offering advanced file and storage management tools suitable for SMBs and enterprise branch offices.

The TeraStation’s compact footprint (170 mm W x 215 mm D x 230 mm H) and 85W power consumption make it efficient for office deployments. Built in Japan with TAA compliance, it supports secure government and enterprise use cases. While RAID modes beyond JBOD are not confirmed, the system’s partially populated configuration allows for tailored deployments and cost management.
