Buffalo Technology
A two-bay desktop NAS with 12 TB of pre-installed storage, RAID 1 redundancy, and a single Gigabit Ethernet port
Capacity 12TB (2 x 6TB)
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.
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.
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.

이 모델의 다른 버전
같은 제품군에서 메모리·쿨러·클럭이 다릅니다 — 결정 전에 비교해 보세요.
The unit is rated at 48W maximum power consumption, so continuous operation will stay at or below that figure.
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.
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.
