I have an older version of Voyager Q. I like it very much.
One weakness though... after around 20 or 30 minutes, the HD becomes very hot. Recently, I got a small USB-powered fan and it solved the problem!
It's not a simple-clean setup with a small fan, but it's kind of fun!
One more thing for the old version, the firewire & USB 2 connection of older Voyager Q, doesn't work with 3TB HD. The eSata works with 3 TB HD.
...make sure that the newer one works with 3TB HD + firewire.
