Small Tree Communications has announced its abcSAN shared storage disk, launching at Macworld 2009 in January. The new SAN (storage area network) disk is a member of Small Tree's GraniteSTOR family, an iSCSI-based Ethernet-attached unit capable of over 600MB-per-second speeds. The disk array arrives with a user interface that features a one-pane window for managing RAID sets, volumes and shares. It can be set up as a SAN or network-attached storage, with 4 and 16 drive configuration to be offered.

The introduction at Macworld will be located at the North Hall booth 3534-G. Pricing and availability has not been announced.
