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!"
Most of these comments show an ignorance on energy issues. A new nuclear power plant will cost $8-12 billion for 1000 MW and will produce power 90% of the time for 30-50 years. A wind farm wiill cost around $2B per 1000 MW and will last 20-30 years. It will produce power around 30% of the time. 1 MW of wind at a good location will produce around 2.5M kWh per year. Do the math on this and you will see why wind is growing by leaps and bounds and nuclear is struggling. Wind needs back up reserve energy but much of that is already in place and is still much cheaper than other sources of energy, especially when the costs for the subsidies involved in coal and nuclear pollution are taken into account. And this strange argument that wind takes up land? There is nothing being done on the land in Kern County where this 3000 MW of wind is being installed. Cattle can still graze beneath turbines or in the midwest, farms can still farm beneath and around wind turbines. Really people, do some more research before putting your opinions into writing.
