Ok, I'm a bit confused. The reviews/benchmarks I've read online place FW800 speeds close to eSATA speeds whereas some people say that eSATA>FW800 in terms of speed. What I want to know is how much faster is eSATA over FW800 in a single drive (no RAID etc.) setup and is it worth getting eSATA over FW800 or is there no difference in both? I'm going to get an eSATA ExpressCard 34 for my MacBook Pro so I'm contemplating on whether to get a eSATA one or a FW800 one as FW400 is not as fast as I want it to be.
