BUFFALO LS220D0802 – LinkStation 220 8TB 2-Bay RAID NAS
Overview
The BUFFALO LS220D0802 is a LinkStation 220 network-attached storage system with two installed 4TB hard drives providing 8TB of total storage. The 2-bay design supports RAID 0, RAID 1, and JBOD configurations for shared network storage and data protection requirements.
The system connects to the network through a single Gigabit Ethernet RJ-45 interface and provides SMB/CIFS, AFP, FTP/FTPS, and TCP/IP network services. A USB 2.0 Type-A port supports compatible peripheral devices and direct-copy functions.
Technical Information
The LS220D0802 uses an 800 MHz dual-issue ARM processor with 256MB DDR3 memory and SATA 3Gbps interfaces for its two internal drives. Its Gigabit Ethernet interface supports 10/100/1000 Mbps auto-sensing operation with AUTO-MDIX.
Supported RAID modes include RAID 0 for combined capacity and performance, RAID 1 for mirrored storage, and JBOD for treating the installed drives as separate storage. With two 4TB drives installed, the system provides 8TB total capacity in RAID 0 or JBOD configurations, while RAID 1 uses one drive's capacity for mirrored protection.
Compatibility
The LS220D0802 is designed for wired network environments using standard Ethernet connectivity and TCP/IP. Compatible client systems can access shared storage through the supported network file services. The USB port is intended for peripheral devices and is not designed for direct connection to a computer.
