[H] USB 3.0 faster than SATA 3Gb/s on HD?

[Anthony Q. Martin]

Is that right?  I have a 1 TB drive in a usb3.0 enclosure running off my 
mobo. Using CrystalDiskMark, I find that the read/write performance is 
faster to a usb 3.0 drive than to an internal drive on a SATA port. In 
some cases almost a factor of 2, but not generally.

Is that right?
How does esata compare?  I currently don't have an esata enclosure 
hooked up so I can't test.
