This is going to be a novice question so forgive my ignorance. I'm looking at purchasing The TB Elite Pro Dual My one question that I haven't been able to find an answer to is this: is there really any benefit in purchasing the TB version when I'm only going to be using it with 7200rpm drives? Will there be a speed increase vs say, Firewire 800? Does Firewire 800 still bottleneck what 7200rpm drives are capable of? Thanks!
