Let the hive mind of Engadget get that for you.
"I finally got a new laptop with a lone USB 3.0 port. I'm now looking at getting a USB 3.0 hub with a power adapter so I can use both of my USB 3.0 hard drives at faster speeds. I've read lots of horror stories where some hubs either don't come with power adapters -- and as a consequence the portable drives don't work with them properly -- or they are designed poorly which results in USB 2.0 speeds. Or, the hard drives keep getting disconnected. Do your readers have any suggestions or experience using USB 3.0 hubs? Thanks!"
Is that 6 copper lines they're bonding? If so, no need to get excited. Pair/line bonding for 6 lines won't ever happen. It's tough enough to get 1 good pair to your house and AT&T is soon going to try 2 in some areas, but outside of that, 6 lines won't ever happen as most of the pairs going down the poles are already taken anyway and it would probably end up costing about the same if not more to condition all those copper lines for each house instead of just running fiber.
I guess its possible for that to happen in other areas, but certainly not in any ATT areas i've worked in. Maybe the Euros will have something though?
Except that 500Mbps over 6 pairs is still over 80Mbps/pair
Which is still very fine by me.
