Quote:It is compliant with PCI Express Specifications 1.1, 2.1.

PCIe supports the following features:
...
Maximum link width is 4, single bi-directional Link interface
...
Support 2.5GT/s and 5.0 GT/s serial data transmission rate per lane per direction
also, tests posted on this forum have shown speeds ~1.5GB/s.

Thank you. I thought it was a bit strange to support only 2.5GT/s for a newer device.
