Pretty heavily committed to Firewire storage drives here. I know about Apple's FireWire to Thunderbolt adapter. But how reliable is it? I assume some sort of data communication conversion and processing is constantly occurring to make it work. So my question is whether the 2012 Mac Mini with it's built-in FireWire capability makes more sense than external conversion required with the adapter for the 2014? There might not be any difference, but technically I'm not sure. Any thoughts?
