USB is also inherently inefficient with a hard drive as the data needs to be converted from the eSATA connection of the hard drive bus to USB.

The protocol conversion speed is insignificant compared to the data rate of a hard drive. USB 2.0 had some issues with the software overhead required to run the port, but that's been fixed in USB 3.0. For all practical purposes there isn't any difference in performance between a SATA-connected hard drive and a USB 3.0-connected one.

It's not until you start getting into SSDs that really need a SATA 6Gbit/sec connection to function at full throughput that the differences between USB 3.0 and SATA start to become an issue.
