Two-bay desktop NAS with 8 TB capacity

The Buffalo LinkStation SoHo 220 is a compact network-attached storage device designed for small offices and home users who need centralised file storage and automatic backup without recurring subscription fees. It ships with two 4 TB hard drives pre-installed in a RAID 1 configuration that provides 4 TB of usable space and protects data against a single drive failure. The unit runs a closed operating system that limits third-party vulnerabilities and includes SSL encryption for secure file transfers.

Single 1 GbE network port

Connectivity is provided by one RJ-45 port supporting 10, 100 and 1000 Mbps speeds with auto-MDIX, plus a single USB 2.0 port for attaching external storage or a printer. The internal drives use a SATA 3 Gbps interface and the system is powered by a dual-issue ARM processor clocked at 800 MHz with 256 MB of DDR3 memory. RAID 0, RAID 1 and JBOD modes are supported, allowing the buyer to choose between performance, redundancy or maximum capacity.

48 W maximum power draw under sustained operation

During continuous file transfers and background RAID maintenance the unit draws up to 48 W from a 100-240 VAC supply, and it is rated to operate between 5 °C and 35 °C. The closed firmware focuses on core NAS functions rather than expandable applications, so buyers who need third-party apps, faster multi-gigabit networking or higher CPU performance for transcoding should consider a more advanced platform.

Questions about this item

What throughput does the single 1GbE port actually deliver when the LS220D0802B is serving files?

The 10/100/1000 Mbps RJ-45 port negotiates at gigabit speed, so real-world transfers top out at the wire-rate limit of that single link.

Which network standards does the LS220D0802B support and what is the highest link speed?

It implements IEEE 802.3, 802.3u and 802.3ab with AUTO-MDIX, giving a maximum negotiated rate of 1000 Mbps.

What physical space and drive format does the two-bay chassis require?

The desktop unit accepts two 3.5-inch SATA drives and ships with 4 TB drives pre-installed in a RAID 1 array.
