I'm detecting some confusion here, that's just a standard SATA connection the dongle has on plug that fits across both sockets, the two on the left.
When fixed internally in a PC the larger socket is for the power lead and the small one for the sata connector, with a dongle it's a combined plug.
I thought the problem was it had a USB C plug for plugging into the PC not the drive instead of a USB2 A type or better and faster USB3 A type, USB2 plus are white, USB3 are blue and plug into the same coloured socket on the PC. don't plug anything onto the 4 pin connector on the drive it will probably blow something up, think it's for testing by the manufacturer.
The Dongle Bill Linked will be fine as it has a USB A plug or as you don't need IDE but just SATA then one like this would do, sorry its Amazon UK link but you can see what you need
