Secure personal cloud NAS

The Buffalo LinkStation SoHo 220 is a two-bay desktop NAS that ships with two 2 TB drives for 4 TB raw capacity. It targets home offices and small businesses that want a subscription-free personal cloud with hardware RAID redundancy out of the box.

Build integration

The unit connects through a single gigabit Ethernet port and a USB 2.0 port for additional storage or printer sharing. A closed operating system limits third-party software exposure while supporting FTPS, FTP, AFP and CIFS/SMB for broad client compatibility. RAID 0, 1 and JBOD modes let the builder choose between performance, mirroring or simple spanning.

Sustained-load behaviour

The 800 MHz dual-issue ARM processor and 256 MB DDR3 memory deliver steady throughput for everyday file transfers and automated backups. Maximum power draw is 48 W within a 5 °C to 35 °C operating range. The manufacturer notes that the LS SoHo 720 offers higher performance and 2.5 GbE connectivity for heavier workloads.

Questions about this item

Does the 1GbE port limit sustained transfer speeds?

The single 1GbE port caps network throughput at 1000 Mbps, so sustained reads and writes cannot exceed that link speed.

What is the maximum power draw and operating temperature range?

Maximum power consumption is 48W and the operating temperature range is 5°C to 35°C.

Are the two 2TB drives already installed and configured?

The unit ships with two 2TB SATA drives pre-installed in RAID 1, giving 2TB usable capacity.
