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!"
Ok, ok, had enough fun? I wrote the original engRish report and stole the picture from a insanely vague Japanese PR release that was not fully released (maybe it was recalled). The Toshiba "Jegway" in the picture is only a 1/2 scale prototype. The "Jegway" is actually a 3-wheel device and may be locked in the folded position so people don't try to ride during testing (Toshiba did not offer any explanation and their Japanese website no details or pictures).
