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!"
well i suppose this might have affected those who have WGA installed. i have a legitimate copy of windows yet find no reason to install software that gives me absolutly no advantage whatsoever.
i do not install software the calls home for no reason WGA included. if i need to download something from MS' site, their alternatives works just as well.
