Thanks guys for all the help.
I never (never) appreciated that one could have FW and USB in the same box. I was also surprised to learn that USB2 is faster than FW.
I am going to hide in a corner and read up on external HDD interfaces. I am ashamed to say that I never fully understood USB interface. Okay back to Google.
