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!"
Come on, why report this rubbish? It's 12lb and only lasts 50 minutes on batteries. I'm guessing that it's thicker than 2". I just don't think the "enthusiast" desknotes are worth it, particularly not this one. Get one with a good notebook chip and you'll triple your battery life, half the weight and less than half the price. Sure, it would be half the speed, but it's still better than living with a luggable.
