I've seen the same thing mentioned for the WD line of drives about it using a proprietary connector, but it looks just like the normal USB 3.0 to me as well. I have one of the Toshiba drives, and the connection is absolutely terrible. It's not just crappy on the side that connects to the drive itself, but the side you connect to a machine is also very temperamental. We ended up with about 6 of them for work, and every single one has issues with the connection. You have to fiddle with them every single time you use it to get the connection to work, and then make sure you don't touch it while moving any files around.
