Buffalo Technology LS220D1202 2-Bay NAS 12TB (2x6TB)

12TB 2-Bay Personal Cloud NAS

The Buffalo LinkStation 220 ships with two 6TB drives installed, providing 12TB raw capacity in a desktop network storage device. It runs a closed operating system on a dual-issue ARM processor at 800MHz with 256MB DDR3 memory. One Gigabit Ethernet port and one USB 2.0 port handle network and local expansion. The unit is new and includes setup media, cables and a power adapter.

Home users wanting simple RAID-protected storage

This NAS suits households that need automatic PC and Mac backup, file sharing and remote access without subscription fees. RAID 1 ships configured for redundancy, yielding 6TB usable space. Buyers who require faster throughput, 10GbE connectivity, expandable RAM or third-party app support should consider a higher-specification platform. The single USB 2.0 port limits high-speed external drive attachment.

Hardware RAID 0, 1 and JBOD modes

The onboard controller manages three RAID levels directly, so drive failure in RAID 1 does not interrupt access to data. JBOD presents each 6TB drive as an independent volume if maximum capacity is preferred over redundancy. No software RAID layer is needed, keeping CPU overhead low on the 800MHz ARM core.
