@Darren, people increasingly use USB to transfer rich media back-and-forth from cameras and many other devices. That’s what I meant when I said download.

@Darren

When it says “download speed” I understand that he meant downloading from a camera or other device, not from the net. Maybe transfering would have been a less ambiguous term.

OK, I must be missing something. USB 3.0 has a full-duplex data transfer rate of 4.8 Gbps, as opposed to USB 2.0’s 0.48 Gbps.

That’s great news for those of us who transfer large files to and from external media, and opens the potential for USB gigabit Ethernet adapters (great for people who use little “net books”).

But what on earth does that have to do with “download speed”? The rate at which I can transfer a file from a network resource to my workstation (the definition of “download speed”) is not limited by USB. Most broadband service peaks at 16 Mbps (0.016 Gbps), and even the new fiber-optic service plans peak out at around 60Mbps (0.06 Gbps). I don’t see how faster USB will help here.
