Two-bay Windows Server IoT 2025 NAS

The Buffalo TeraStation WS5220DN08W5 is a desktop network-attached storage device running Windows Server IoT 2025. It ships with two 4 TB SATA drives installed for 8 TB of total capacity. An Intel Atom C3338 dual-core processor at 1.5 GHz and 8 GB of DDR4 memory handle file services and applications. Small businesses and remote offices needing a ready-to-run Windows storage platform are the target users.

Verify network and expansion needs

Confirm your switch or router has a free 10 Gigabit Ethernet or Gigabit Ethernet port to use one of the three RJ-45 connections. The unit provides two USB 3.2 Gen 1 ports for external drives or backup devices. Internal expansion is limited to the two SATA bays already populated; the system supports up to 48 TB of raw drive capacity when larger drives are installed.

Included accessories simplify deployment

A Cat 6a Ethernet cable is supplied for immediate 10 GbE connectivity. The front-panel key secures physical access to the drive bays. An SD card containing setup media lets you initialise the operating system without downloading images. The quick setup guide walks through the first-boot configuration steps.

商品問答

What comes in the box with the WS5220DN08W5 and what must be purchased separately?

The box includes the TeraStation WS5220DN08W5 unit, an AC cable, a 6a Ethernet cable, a front panel key, a warranty statement, a quick setup guide and setup media on an SD card. Two 4 TB SATA hard drives are already installed, so no drives need to be bought unless you want to expand to the 48 TB maximum.

How do I decide between the available drive configurations for this TeraStation model?

This specific model ships with 8 TB total capacity provided by two pre-installed 4 TB SATA drives in the two bays. The hardware supports up to 48 TB, so the only decision is whether the factory 8 TB meets your needs or if you plan to replace the drives with larger SATA units later.

What does the 10 Gigabit Ethernet port mean for actual file-transfer speed on this NAS?

The 10 Gigabit Ethernet port can move data at up to 10 Gbps when connected to a compatible switch and client, while the two additional Gigabit Ethernet ports provide standard 1 Gbps links. Real-world throughput will depend on the Intel Atom C3338 processor, the SATA 600 drives and the RAID level chosen.
