I have a bunch of USB A to Mini B cables and a single USB A to Mini A cable. I have lost track of where they come from. The two types both look exactly the same with the USB A side having a white plate inside and the shape of the Mini plugs are the same too. So the only difference is that the Mini B plugs are black inside and the Mini A plug is white inside, like the plugs shown here, but my Mini A looks exactly like a Mini B except that it's white.
What is the difference between my USB Mini B and Mini A cables? Do they have the same performance when plugged between my external hard drive and my computer? If not, which type would be better and how?
Should I trust the shape or the color? Because, again, my Mini A plug looks exactly identical to a Mini B plug except for its white-colored plate inside. So could it be that my Mini A is actually just a white-colored Mini B?
