Multi-bay HDD enclosures and your WD Live SMP

Ok so I have the SMP and 3 WD Essential external HDDs.  The SMP has the latest firmware.  I need to add another drive to make room for more movies in my media library.  I am not opposed to just getting another external drive, however I am interested in just putting everything into a multi-bay enclosure.  My issue is I have not found any answers to whether or not this can be done with the SMP.  If so what should I be looking for in an enclosure?  Port multiplying, a certain RAID protocol?  Looking for a little guidance from some of the gurus.  Any info you can give would be greatly appreciated. 

Hi,

It might work with a USB multi-bay hdd…

SMP support up to 4 TB with the latest firmware.
