I'd like one for professional use (Okay two enclosures actually!) with a "tray" system where you can pull the drives out and don't have to take apart the whole enclosure to access the drives. Two drives. I was gonna get a G-Safe but apparently they've been discontinued and aren't available in Europe anymore... I don't have USB3 on my Mac Mini so I'd need Firewire 800 or Thunderbolt. Thanks!
