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!"
Microsoft NOW putting new heatsink in the 360, but, nobody knows if they are putting them new units, elites, or just the trash refurbs.
Still no word on the status of replacing the dreadfully inadaquate and defective dvd drives. http://www.xbox360defective.com Notice video where they tear down the ELITE and show same dvd drives, same sucky heatsink.
