BUFFALO LS720D0402 – LinkStation 720 4TB 2-Bay 2.5GbE NAS
Overview
The BUFFALO LS720D0402 is a LinkStation 720 desktop network-attached storage system with two installed 2TB hard drives for 4TB of total capacity. The two-bay platform provides RAID 0, RAID 1, and JBOD configurations for centralized storage, performance, or drive-level redundancy.
The system includes a 2.5GbE RJ-45 network interface, a hexa-core 1.3GHz processor, and 2GB of memory. Buffalo specifies RAID 1 as the factory default configuration for the LS720D0402.
Technical Information
The LS720D0402 uses SATA 6Gbps interfaces for its two internal drives. Supported RAID modes are RAID 1, RAID 0, and JBOD/normal mode. In the factory RAID 1 configuration, the two 2TB drives are mirrored, providing approximately 2TB of nominal usable storage before filesystem overhead.
The single RJ-45 network interface supports 2.5GBASE-T, 1000BASE-T, 100BASE-TX, and 10BASE-T operation with AUTO-MDIX. Supported network file services include SMB/CIFS and FTP/FTPS, with TCP/IP used for network communication.
Three USB Type-A ports are provided: two USB 3.2 Gen 1 ports supporting up to 5Gbps and one USB 2.0 port supporting up to 480Mbps. Buffalo specifies the USB ports for peripheral connections and not for direct computer-to-NAS connections.
Compatibility
The LS720D0402 is intended for wired Ethernet environments with compatible 2.5GbE, Gigabit Ethernet, Fast Ethernet, or 10Mbps infrastructure. A compatible 2.5GbE network interface and switch are required to operate at the maximum 2.5Gbps network rate.
Buffalo documentation identifies compatibility with Windows 11, Windows 10, Windows 8.1, supported Windows Server environments, and Mac OS X 10.12 or later. The system can also serve compatible DLNA and DTCP-IP digital-content environments.

DC Supplies Product Note
The LS720D0402 is the 4TB configuration of the LinkStation 720 2-bay platform, using two 2TB drives. For procurement, retain the complete LS720D0402 MPN because the LS720D series also includes different capacity configurations and separate regional or retail variants.
