Crunchgear compared the performance of several eSATA and USB 3.0 storage devices and concludes that, at least for now, eSATA is still the fastest external interface.
This will likely change over the next few years as computer hardware catches up to USB 3.0. The situation is nothing new. Most up and coming technology is limited by current hardware. USB 2.0 went through the same thing years ago. But if you’re looking for a reliable and fast external hard drive right now, forget USB 3.0 and instead look at eSATA drives.

Bad test. The details are sketchy, but the test uses a pc card based esata, which likely has bandwidth issues going into the notebook as pc cards max is barely half the USB 3 spec. And with overhead it probably doesn't even hit that.
ESATA on notebooks however has a direct channel to the DMI and hend the other ports and CPU. It's going to be faster simply by virtue of it's connection. An internal notebook NEC controller on a pci-e x1 2.0 channel is going to show dramatically better results. Try one of the new HP's or the Dell M6500 with USB 3 and you'll see quite a different story.
USB 3 is at LEAST as fast as ESATA and likely 2-3x as fast when SSD's go into mobile docks. Couple that with the convenience of a single cable power connection and ESATA is so last century.
