There are a variety of SATA enclosures that will work with the ADS3GX4R5-EM host adapter using the SiI3124_2.0.1_Sil_Pkg Macintosh driver. Addonics provides a Storage Tower that can be setup with a 5X1 Port Multiplier (model ST5X1PM) or used with individual had drives. It can be found here: http://www.addonics.com/products/raid_system/ast4.asp
