USB 2.0 to 3.0

post #1 of 19
Thread Starter 
Does USB 2.0 perform better on 2.0 or 3.0? I am getting a new Lian Li case that has USB 3.0. It also has a USB 3.0 to 2.0 adapter. Would it be okay to just use 2.0 devices on it without any decrease of performance?

A USB 3.0 to USB 2.0 adapter? I've never heard of that before. Is it an external adapter or internal adapter?

You will get the same performance running a 2.0 device off a 2.0 port or a 3.0 port.
I've tried.

I doubt you can even get USB 3.0 since your motherboard doesn't support it. Unless you have an add-in card.

USB 3.0 is backwards compatible with 2.0.

This.

I dunno what the dealio is with the "adapter" the OP mentions. 2 and 3.0 are the same physical connector.

I believe the adapter is if your motherboard doesn't support usb 3.0. Looks like it will allow you to connect it to the usb 2.0 pins on the motherboard.

So you're asking if you use that adapter if you will have any performance decrease using 2.0 devices? Nope. Usb 3 is identical to usb 2 except there are extra wires to carry 3.0 data. With that adapter those 3.0 wires won't be hooked up making the port no different than any usb 2 port.
