u guys may also be interested in the performance of all these product.
just throw a simple example. As Micro PCI E 2.0 is equal to a PCI E 2.0 X1, thus the bandwidth would be 5Gbps, which is the key factor here to limit the performance. Comparing to a X16 interface, video card performance may drop nearly 30% under full load.
refer to more detail on PCI express or Thunderbolt interface: google: external graphic card
as for the performance test, sry that I didnt save that link, google something like: PCI E Graphic card test.
