Re: Mac Pro 5,1: I need USB 3 but no PCIe slots left
Haven't read specs of your chassis so I'll just ignore that, no idea how the "variable bandwidth" would work in that piece of gear.
Just saying -- even with variable bandwidth, or "dynamic lanes" or whatever -- if the host card is x4 then you can have x1 from USB3 card (500MB/sec) and x3 from SSD card (1500MB/sec) if you transfer from one to another. Or full power from USB3 (x2) and another x2 from SSD card, which means 1000MB/sec max transfer rate. The data goes to host computer and back, not from chassis slot to chassis slot. And while doing such transfer any other slots you may have in the chassis have zero bandwidth.
This is an imaginary situation though, because I don't have the specs.
