Personal cloud NAS for home users

The Buffalo LinkStation 220 is a two-bay desktop NAS that arrives with two 2 TB drives pre-installed. It connects to a network through a single gigabit Ethernet port and offers a USB 2.0 socket for external storage. The unit runs a closed operating system designed for simple file sharing and automatic backup from Windows and mobile devices without subscription fees.

4 TB raw capacity with RAID flexibility

The 4 TB total capacity ships configured in RAID 1, providing 2 TB of usable space with drive redundancy. Users can switch to RAID 0 for the full 4 TB or use JBOD for independent volumes. The SATA 3 Gbps interface and 800 MHz dual-issue ARM processor with 256 MB DDR3 memory deliver adequate throughput for everyday file access and media streaming, while heavy multi-user workloads will saturate the single gigabit link.

Quiet operation within standard office temperatures

Maximum power draw is rated at 48 W from a 100-240 VAC supply, and the operating range spans 0 to 35 °C (41 to 95 °F). The fanless chassis relies on passive cooling, so acoustic output remains low during typical backup and streaming tasks. Sustained heavy transfers may raise internal temperatures toward the upper limit, but the device is built for continuous operation in normal indoor environments.

Questions about this item

Will the single 1GbE port and USB 2.0 connection keep up with my older Windows 7 PC and USB 2.0 external drives?

The NAS links at 10/100/1000 Mbps and supports Windows 7 32-bit and 64-bit, so file transfers run at wired Gigabit speed while the USB 2.0 port works with existing USB 2.0 drives at their native rate.

How can I confirm the RAID 1 mirror is healthy after first boot?

Log into the web dashboard; the RAID status screen shows the array state as Normal when both 2 TB drives are synchronised, and the front LEDs stay solid blue once the mirror finishes its initial build.

Does the box include the two 2 TB hard drives, or must I buy them separately?

The unit ships with two 2 TB SATA drives pre-installed and configured in RAID 1, giving 2 TB usable space; only a network cable and power cord are needed to start.
