BUFFALO LS220D1202 – LinkStation 220 12TB 2-Bay RAID NAS
Overview
The BUFFALO LS220D1202 is a LinkStation 220 two-bay network-attached storage system with two installed 6TB hard drives providing 12TB of total storage. It is designed for centralized file storage, network sharing, and backup across compatible wired network environments.
The two-drive architecture supports RAID 0, RAID 1, and JBOD configurations. RAID 1 provides a mirrored 6TB usable capacity, while RAID 0 provides up to 12TB of usable capacity before filesystem overhead.
Technical Information
The LS220D1202 uses an 800MHz Marvell Armada 370 dual-issue ARM processor with 256MB of DDR3 memory. The two internal drives use SATA 3Gbps interfaces.
Network connectivity is provided through one RJ-45 Gigabit Ethernet port supporting 10/100/1000Mbps auto-sensing operation and AUTO-MDIX. Supported network services include CIFS/SMB, AFP, HTTP/HTTPS, and FTP.
The system also provides one USB 2.0 port with a maximum interface data rate of 480Mbps. Actual transfer performance depends on the connected device and operating environment.
Compatibility
The LS220D1202 is intended for TCP/IP Ethernet networks and supports file access from compatible Windows and Mac systems through its supported network file services. Buffalo documentation lists support for Windows client and server operating systems and Mac OS X versions supported by the product generation.
The NAS uses a standard RJ-45 Gigabit Ethernet connection rather than a 2.5GbE or 10GbE interface. Network performance is therefore bounded by the available Gigabit Ethernet link and the capabilities of the connected network infrastructure.

DC Supplies Product Note
The exact LS220D1202 is the original LinkStation 220 12TB configuration using two 6TB drives. It should not be substituted with the similarly named LS220D1202B, which is a separate manufacturer part number in the LinkStation SoHo variant.
