Wired here is what one usually uses for larger external hard drives with USB3, there are also many other devices like printers, scanners and many other things that use this connector, but pretty much all 3.5" external hard drives with USB 3.0 use a cable like this to join to your Mac.

The cable comes in the normal USb 3.0 blue color, it's 1.5m long and in good quality, there's not really any quality difference to USB cables, either then they don't work, the cable here is built so it works long, especially when you consider that a USB 3 hard drive cable cable as this usually does not need to be moved more than a few times a year, therefore it does not get worn as other types of cables do.

The cable supports full 5 gbps connection between the USB device and your Mac with USB 3 port, it has all newer macs fortunately. The cable is also backwardcompatible with USB 2 and USB 1, here the data connection is somewhat limited and it's power consumption too so if you plan to use the cable with a Mac with USB 2.0 then make sure the USB device gets its power from somewhere else from , this type of USB cable, namely USB 3.0 type B is usually never used in portable hard drives, so you are probably assured this so here you probably can't make a mistake.
