In terms of transfer rates: eSATA > Firewire > USB
USB is more universal than the other two, if that's a concern. "Do those adapters slow transfer speeds? Would I be better off using the drives USB 2.0 port to connect it to my computer?" I can only assume that those adapters have some sort of affect on the transfer speeds, but I do not have those ports, nor do i have any adapters like that, so to presume to answer you, i would best leave it to some of the others on the list with more knowledge than I.
