The Kingwin EZ-Dock is the only way to go as far as speed with swapping in and out drives from an external enclosure. It even puts the old terminology of "external enclosure" into question. The Kingwin dock gave us no issues or problems at all. It's plastic construction was lightweight but did not feel flimsy. What really makes Kingwin's $25 unit shine is the inclusion of the PC Clone EX Lite software and the integrated one touch back up. A system back up at a single touch that the end user predefines is fantastic.
