BUFFALO LS220D0402B – LinkStation SoHo 4TB 2-Bay Gigabit NAS
Overview
The BUFFALO LS220D0402B is a LinkStation SoHo 220 desktop NAS configured with two 2TB hard drives for 4TB of installed storage. The two-bay system is designed for small-office and home-office network storage, centralized file sharing, and backup applications.
The factory configuration uses RAID 1, providing a mirrored storage arrangement with 2TB of usable capacity from the two installed drives. RAID 0 and Normal/JBOD operation are also supported when a different storage configuration is required.
Technical Information
The LS220D0402B uses a Marvell Armada 370 800MHz dual-issue ARM processor with 256MB of DDR3 memory. Network connectivity is provided through one Gigabit Ethernet RJ-45 port with 10/100/1000Mbps auto-sensing operation. One USB 2.0 Type-A port is available for supported USB devices.
The NAS supports TCP/IP networking and SMB/CIFS, AFP, and FTP/FTPS network file services. The two internal drives use SATA 3Gbps interfaces.
Compatibility
The LS220D0402B is compatible with supported Windows and macOS client environments and provides standard TCP/IP network connectivity through its Gigabit Ethernet interface. Supported network file services include SMB/CIFS, AFP, and FTP/FTPS.
BUFFALO identifies the OP-HD2.0T/LS as the replacement hard drive for the 4TB LS220D0402B configuration. Drive replacement requires the NAS to be powered off; this model does not support hot-swapping.

DC Supplies Product Note
The LS220D0402B is a 4TB configuration using two 2TB drives and ships configured for RAID 1. Because the chassis has only two drive bays and does not support hot-swapping, plan drive replacement as a powered-off maintenance operation.
