Yes thats what i mean have each port max out and not share the total 480 / 5. Each hard drive i add to my 4 port pci card the transfer speeds get halved it seems like. Anyone know of a good max speed per port card ?I've never seen anything that could saturate the theoretical maximum throughput of a USB 2.0 bus, although I've noticed USB 3.0 devices typically greatly exceed speeds of USB 2.0 devices when run on the same USB 2.0 bus. That might be the best you can do.
It would be a remarkable achievement if you could reach 480 mbps. I doubt it's actually possible, but good luck!
