5 out of 5 eggs

Pros: Twice as fast as built-in USB 2.0

Cons: Much slower than USB 3.0 standard - not cards fault, limitation of legacy PCI Bus on older computers.

Price for card seems high

Other Thoughts: This card is twice as fast as the built in USB 2.0 on my computer. However it is much slower than the USB 3.0 standard. This is not the cards fault, it is the limitation of the legacy PCI bus. This card provides enough power to power my external 2.5" laptop hard drives. You must connect an internal power source to PCI card. To achieve the best performance with this card, limit the amount of devices connected to it. Example - My keyboard, mouse, non USB 3 devices are running off my USB 2.0 ports. When I was running these off the USB 3.0 card it dropped transfer rates by 10MB/s!
