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!"
Anyone worried about missing the movie after the 24hr timer starts:
Turn your system clock back.
Seriously, it works. I'm sure it won't after a patch or two, but it does now. So if you want to watch a movie rental for a week solid untill your eyes bleed, you can.
Enjoy! :P
