Is this the real USB 3.0
I just bought a Dell Inspiron 17R - N7110 Laptop. One of the main reasons I bought this paticular model was the fact that it had two USB 3.0 connectors on the side. I have nothing that is USB 3 to verify the speed, but the more I read about it, the drives are just coming out and it almost seems kinda early for Dell to have this on a laptop? Here is the entry in the Dell manual for this model:
USB 3.0 connectors (2)
— Provide faster data transmission between your computer
and USB devices.
The symbol for the connectors on the side of the laptop is a small graphic with the letters "SS". When I was reading about verifying a USB 3.0 device it says it has to have the certified SuperSpeed USB 3.0 logo. Sounds good? How can I verify these USB 3.0 connectors pass data from a USB 3.0 HD at 5 gb per second, wow fast. Does anyone else have one of these and knows, thanks

I had a similar curiosity because I have a USB 3.0 3TB external drive in the box on my desk waiting for Father's Day. Here from a review on CNET from last year
"In the USB 3.0 write test, the drive scored 72 megabytes per second compared to 24.7 megabytes per second of the Iomega eGo, which is the second fastest. In the USB 3.0 read test, the BlackArmor PS 110 USB 3.0, interestingly, did worse than its write test at 59.4 megabytes per second. Still, this is about twice the read speed of even the fastest USB 2.0 hard drives. With USB 2.0 hard drives, generally the write speed tends to be slower than the read speed. This is reversed in the case of the BlackArmor PS 110 USB 3.0.
When connected to a computer via a USB 2.0 port, the BlackArmor PS 110 was still among the fastest USB 2.0 external hard drives with a write test speed of 25 megabytes per second and the read test speed of 29.6 megabytes per second.
There will be more USB 3.0-based external hard drives coming out in the near future and we can't wait to see how the BlackArmor PS 110 USB 3.0 will stack up to them. For now, it's by far the fastest USB external hard drive we've seen."
Bottom line: There are many factors in reading and writing to external 3.0 devices. The best I have found from others' results are that you are experiencing 3.0 speeds if you get between 50 mb/s and 110 mb/s.
HTH
Update...
Prior to shutting down for the night, when going through the Safely Remove/Eject, Windows came back with a nasty gram saying that a program was using it so it wouldn't eject. Went ahead and shut down the computer.
This morning, turned the computer on, the lights flashed on the Waves buttons above the keyboard, and turned off. Didn't even get to the Dell screen. Tried again...same thing.
Disconnected the HD, turned computer on and it booted normally. Plugged the drive in and it is performing normally.
Weird?!?

These are the first generation of USB 3.0 -- with full Intel chipset support, yes. Earlier models had add-on Renesas controllers (Renesas being one of the chipmakers that was hard-hit by the Japanese earthquake/tsunami).
