Will a USB 3 cable work on an old Dell dimension 3000 desktop?

I'm looking to get an external hard drive that uses USB 3 technology, and was just wondering if it would even work on my Dell dimension 3000 desktop?

Hi linux-user
Usb3 is backwards compatible , which means it can plug into and run on usb 2.0 or usb 1.0 ,
it just means that the speed of the data transfer will not be as fast on usb 2.0 or 1.0 as it would on usb 3.0 but it will still work

well, if you have a usb port you can plug it in and use it, but you will run at the lower speeds + your computer is pretty old (this also causes low speeds)

Also check if your OS can support it
on the other hand you can get a external HDD anyways because you might have to upgrade your rig someday
