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!"
Don't get all this "how Orwellian" shit. You do all realise people were already watching the cameras don't you? They're not there for show. How is the fact that the cameras have speakers attached more of a privacy issue? If anything it's less of one because it makes you aware you're being watched. As for CCTV in general that's a whole other argument.
