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!"
also im skeptical about this too (in studios actually bothering to take the time to do it while many of the bd players dont even have ethernet... the samsung for instance)
its its something that is not avaliable on every bd player i dont see too many studios bothering to do it atleast for now (but it sounds like that stuff is pretty far off with hd-dvd as well)
