USB powered drive usually mean SLOW rotational speed i.e. 5400 RPM . NOT the normal 7200 RPM internal drive speed. This affects the data transfer rate,backup speed and read/ write time. Having a power brick has advantages, fast drives ,even up to 15000 RPM if you swap out existing drive with a 15K rpm driveSlow drive are a dying breed and R & D is NOT going into 5400 rpm drives by makers.

USB, no AC mains needed. Needs a powered USB port, not an unpowered port. Many laptops have one or two of each.

For a laptop, I'd ask around for an external hard drive that shuts off when it is Ejected. I have to shutdown my desktop to get the external HD to turned off so I can safely unplug it.Yes, the one I got at Best Buy came with USB cord. Running Windows 7 my USB 2.0 port was compatible.

Yes one is for power the other power/data. I am running the drive on the data cable only. It did not run from the HUB without both plugged in, so I plugged the data cable direct to my laptop and it works just fine without the power cable.

No, it does not, but small external CD/DVD drives that can be powered through the USB are available, many under $50.

Mine came with a power brick, for what it's worth. I believe that this hub corrupted my external usb 3.0 hdd, and pretty much killed it. Don't know this for a fact but I don't use it anymore.

No, it's intended as a desktop drive, meaning the external power supply is needed. But it's worth checking out LaCie's portable HDs. I have a 250GB Porsche-designed one that's been a workhorse for years.

You are correct on your question. I don't use the power cable for my external hard drive

No power adapter. Just the cable from the external hard drive to the computer.

So if I'm understanding your question correctly, you can plug in a power adapter into the mini USB port to charge the device and at the same time use the USB 2.0 port to power and use an external powered USB hard drive.

This drive is USB powered - it actually features dual USB connections in case one is underpowered on your computer. There may also be an option to use a separate power supply but I have not tried that.

Yes it does, the cable has 2 USB heads on it to draw extra power if necessary (there is also a 5v socket on the drive where you can plug in a 5v power supply if even that isn't enough)

The computer has two usb ports that can be used to connect an external hard drive

I believe the drive is powered by legacy usb 2.0 standard interface. The other end of the connector is usb 3.0 peripheral interface.

The end that plugs into the hard drive is mini USB. Do not use third party USB cables with this hard drive, the mini USB plug on those adapters is too loose.

It uses two USB ports to power micro USB devices like portable external hard disks or external DVD burners, so you have separate USB for data and power

To my knowledge, the larger ones (1TB +) seem to have external power. The smaller ones (less than 1TB) are just powered by USB. Those are the ones I have anyway.
