Two-bay desktop NAS for small offices

The Buffalo LinkStation SoHo 220 ships with two 6 TB drives pre-configured in RAID 1, giving 6 TB of redundant storage out of the box. It connects through a single Gigabit Ethernet port and a USB 2.0 port for additional backup targets. The closed operating system limits third-party exposure while providing SSL-encrypted file transfers and folder-level permissions for local and remote access.

Sustained workload behaviour

The dual-issue ARM processor running at 800 MHz with 256 MB of DDR3 memory handles everyday file serving and automatic backup tasks without thermal throttling up to the rated 35 °C operating limit. Power draw peaks at 48 W under full drive activity, and the fanless chassis relies on passive convection to keep the internal SATA drives within their specified temperature range during continuous operation.

Installation and common pitfalls

Setup is performed through a web browser using the NAS Navigator utility; no software installation is required on client machines. The most frequent issue is forgetting to switch the front-panel RAID mode selector before first boot, which locks the array into the shipping RAID 1 layout. A second common oversight is leaving the USB 2.0 port unused when a scheduled off-site backup drive could be attached for extra redundancy.

Questions about this item

How much power does the LS220D1202B draw when it runs 24/7?

The unit is rated at 48W maximum power consumption, so continuous operation will stay at or below that figure.

What must I already have to get the 1GbE port and the USB 2.0 port working?

You need a router or switch with a free RJ-45 jack and a standard Ethernet cable, plus any USB 2.0 device you want to attach.

Will the SATA 3 Gbps bays and the ARM 800MHz processor keep up with my older Windows 7 or Vista PCs?

Yes — the NAS supports Windows 7 and Vista (32-bit and 64-bit) and the gigabit link is the limiting factor, not the internal SATA speed.
