I think, generally speaking, a SATA drive plugged into a SATA port
will always be the fastest possible connection. By using a USB adapter
you're adding an additional layer of overhead to the process (the
adapter translating between USB and SATA, plus any loss of
functionality due to incompatible features like Nikos mentioned).

But if you're wonder what the speed difference should be (if the
difference you're seeing is normal or not) I can't say... I can say
USB3 is faster than USB2 for sure, but I haven't personally compared
to eSATA. :)
