'Put another way, imagine a delivery service began using larger vehicles to transport mail sure, they could get more on each delivery, but it wouldn’t get the packages to their destinations any quicker. This is a pretty good explanation between USB 2 and USB 3: That would not even be possible, because USB is a digital signal, it either works or it doesn't. If that is not the case, you have two malfunctioning USB hubs in both PC's you tested on. It's most likely in your head (100% placebo). I can guarantee you that there is no difference, and should there be any, USB3 is better. If there was a difference (there is not) you would need a highspeed camera and other technical equipment to measure it. In almost all cases, USB 3.0 ports are blue while USB 2.0 ports are black or white in color (see image. Color is the key to telling the difference between USB 2.0 and 3.0 ports.

Second, there is absolutely NO WAY IN HELL that you can actually 'feel' a difference. However, USB 3.0's improved charge speed still pales in comparison to a wall charger (Note 3's default wall charger is rated at 2.0 A). USB 3 is MUCH faster than USB 2, plus USB 3 can even do asynchronous polling - not that it matters much, because mice use VERY LITTLE bandwidth. If you get 200mbps or more, you should be jumping from joy.First of all, you're wrong. In the wi-fi world, the marketing can say they sell you a 'gigabit ac1750 router (or adapter)', and in real life you may well end up with just 100Mbps or slower data throughput. Wireless is not like wired Ethernet, where saying 100Mbps really means that you will actually see TCP/IP data transferred nearly at that rate. You see, the wireless data transfer rates are basically a big marketing scam because half of more of that data transfer rate will disappear due to weakening signal with distance or on the physical layer chatter. In other words, a lot less than USB2 can handle. At TCP/IP level, the throughput will be much lower, even if the distance is short, somewhere in the neighborhood of 100-300mbps, depending on your luck.

However, much of that number pertains to the 'physical layer' information transfer, the chatter that ensures that your data is transferred accurately, under optimal condition (e.g. Let's say we're talking about a two stream AC device, so theoretically it's capable of 867mbps throughput in 5GHz band. You think you need USB3 to drive a 802.11ac network adapter at full speed? Please.
