Synology (http://www.synology.com) has released two new rack-mountable NAS models, the RS212 and the scalable RS812.

The RS812 is the successor to the 1U RS411, but with an advantage. Improving on its predecessor, the RS812 can scale out to eight drives by attaching the RX410 expansion module. This allows businesses to purchase only the required capacity upfront, and scale as needs dictate.

The RS212 represents a new RackStation design. The 2-bay 1U NAS is Synology’s first server designed to fit in a 2-post rack, such as common LAN racks. The RS212 has a more robust design that can help to reduce cooling costs, as it can operate in environments ranging from 0-45 Celsius, says Jason Bonoan, product marketing manager at Synology America Corp.

The RS212 costs under $500 and the RS812 is under $800. The two RackStations sport Synology’s DiskStation Manager (DSM) 3.2 operating system.
