Hello. I have a 2010 MacMini and I usually need the entire USB 2.0 bandwidth for streaming digital HDTV content. But I also want using an external backup unit, so I was planning using the obsolete FW800 port which seems to be the ideal solution. So I need advice for an affordable and reliable 2.5" firewire 800 unit. Another option would be some kind of USB3 to FW800 adapter. I guess it would be a more expensive solution though. Thanks in advance!
