Re: How do I find out how many USB 3.0 ports I have?
Blue tabs are USB 3.0. Non blue tabbed ones are USB 2.0.
A good way to test is to use a USB 3.0 device such as a flash drive, and plug it into each slot. The USB 3.0 slot will "just work" while the 2.0 slots will pop a bubble up in Windows that says "This device can perform faster..."
