USB 3.0 Cards
What is the difference between USB 3.0 cards with power supply connectors, and those without? When would you need a card with a power supply connector and when would you need one without? Does either or have a speed difference even though they both claim 5gbps?
Why don't they point these difference out when selling the product? As many boxes as I have seen, not once have they mentioned the difference or plus side/lack performance to either one.
Thanks!
