USB Confusion: What plugs into what?

I've very confused over 'USB'. It appears to be a connector type, a data transmission type, a cable type and possibly other types too!


I get confused between USB1, USB2, USB3, USB-C, etc.


I am specifically trying to work out whether an external drive at https://www.amazon.co.uk/G-Technology-G-DRIVE-Mobile-USB-C-Silver/dp/B07DK2LPDD will plug into old Macs (with old-style USB ports) and new Macs (with new style USB ports) alike or whether adapters are required. And, if so, which adapter is needed.


It claims 'USB-C ready; USB 3.0 and Thunderbolt 3 compatible'.


Can anyone guide me, please?

As for usage, it should work right-out-of-the-box.


As the Site Reads:

  • Includes both USB-C and USB-A cables for universal compatibility with USB-C and USB 3.0 computers.” and “Perfect for Mac and Windows


It comes with all cables. So, you will be fine with the purchase.

So USB stands for Universal Serial Bus, and through the ages it has experienced several upgrades in speeds and some in size.

It started of from usb 1.0 to 2.0 to 3.0 to 3.1 etc and some of them have different types

Such as type A or type C, male and female, now this may seem confusing so I have attached a little image to try and show you the different generations and the speeds that come with them, for example you can use a usb 3.0 usb type A with a port that was designed for usb 2.0 but you will only have the speed that would have been available for usb 2.0, if that makes sense? So the port will not go the same speed if the usb you are trying to use is designed to be higher speeds than what the Computer has, and vice versa, USB type C is more commonly seen on android devices and has more versatility compared to type A as it can also be used as a power cable and can be used to charger other devices,


So when it says USB-C ready it means that it can be connected to a port that takes usb c connection and also thunderbolt because it is the same physical but it won't be the same speed




Hope this helps


Many thanks

Today new Macs's only have the USBC port, in order to connect to older USB devices— you need a dongle:
