I illustrate this below where I do an import of 50 Nikon D3x RAW files using an unpowered and a powered USB3 card. The PCI slots provides insufficient power and a power line has to be run to the card’s male Molex socket for best functioning. The card may work but, if it does, it will be well below capacity. System Profiler will recognize this card once it’s inserted in a free USB3 slot. The big black cuboid at the top of the card is a 4-pin Molex male socket to which we will have to route power. The ‘F’ in the model designation refers to the Fresco chipset. This version of the Orico uses the Fresco chipset and can be found at Amazon in the 2-port version for $18, or the 4-port for $33.
The Orico PFU3-4P or 2P Four/Dual Port USB3 PCIe card for the Mac. This is the card we want – it comes in 2-port and 4-port versions:

This article only addresses users of Mountain Lion 10.8.3 or later, which comes with drivers for the Fresco chipset used by the card I have installed. At this time there are no PCIe cards which provide TB, but there is a handful which easily add USB3. However, in its apathy, Apple missed adding some modern technology to the Mac Pro from which it can benefit. Other than that the 2009 and current 2012 machines are identical a fact which, once I spotted it, clued me in to the tremendous value proposition offered by the 2009 model. External TB enclosures are very costly and, for most, USB3 is just fine offering half the speed at a fraction of the cost.Īpple was especially lazy in upgrading the Mac Pro, with the 2009 model profiled in these articles identical to the 2012 except for CPU upgrades (thank you, Intel) and one firmware upgrade which allowed the use of 1333MHz memory and accepted 12-core CPUs. The PC world, with its huge – if falling – volume has not exactly embraced the technology and until it does price will remain stratospheric. It’s premature to say that Intel’s Thunderbolt will become the standard for connecting external devices to computers.
