Unsupported (by Apple) enclosures have a certain appeal. But I would rather wait for a supported solution and not upgrade until there is one. My preference (what I have on hand) is SATA III SSD's so I'm stuck waiting for that product. Akitio and OWC (MacSales) seem to be the only ones in the offing (promise ware). The other boxes (docks with breakouts, single drive units, etc. listed as made for Windows) are merely propagating the fiction that is Thunderbolt 3, at least on the Mac side, right now.
