I will be migrating off of my 2008 Mac Pro with 4 bays of drives (1 SSD / 3 HD). Yes 10 years! Had a few questions on external storage on new mac mini that perhaps others may be contemplating. 1) Any recommendations on enclosures. Is the Thunderbay 4 from OWC reliable and speedy? Do I need the Thunderbolt 3 version, Thunderbolt 2 version, would it make any difference? Are there better options out there? 2) How would the speed of this option (with SSD), compare with the SSD internal on the Mac Mini? 3) Is there a thunderbolt 2 or 3 external hard drive that actually leverages the speed of these pipes? thanks!
