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.

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)

Marginal USB power is ALWAYS a risk with drives that run off USB power. I use my portables to hold maintenance and diagnostic tools. They get plugged into different machines every week, and you never know how much power those machines will be supplying. Some machines (especially laptops) just don't put out the power required to run many drives, and some drives suck down more power than others. When you hear the metronome noise, that's an indication that there isn't enough power. Worse, I have had portable disks work fine for a few weeks or months and then start the metronome noise. When I see that a drive "doesn't need a power cable" I always look for whether it comes with a power jack ANYWAY. That way, you can always add wall power if you're having problems. The best deal of all (as far as reliability) are drives like Other World Computing's, that "don't need a power cord" but come with a power jack AND a power adapter for the same price. That way you can run it off a marginal laptop, an unpowered hub, or whatever you need to.

Drive is powered by the computer (device) it is attached to. There is not external power or plug to attach one.

It comes with a power adaptor and a USB cable. The power adaptor is required to power the disk drive.

I ordered a portable external hard drive that uses a USB. Do not know what you a referring to.

It uses a USB 3 cable that comes w/ the drive. I attach it to the USB 2 port in my laptop and runs well. However I am uncertain if the port to the drive itself is proprietary. I have not tried it on other portable drive. In any event, the cable comes w/ the drive.

Western Digital recommends plugging the external hard drive directly into an outlet (don't use any line filters or power strips). Once computer is at the desktop, plug into the outlet - wait several seconds and then plug in the Firewire cable from the HD to the computer - it should power up then. You may need to shut down your computer, and then re-do the above when the computer is at the desktop.

It uses a mini USB. I know its not common in things other than portable USB hard drives and hubs, but a cable is included in the box and replacements can be had for cheap.

I believe it does require a special one. The difference is the computer USB cable has two plugs, one for the drive, and the other for the power. Perhaps one may be available through Cyberguys. http:/www.cyberguys.comLeo

Yes, this unit includes a short USB cable to connect to your computer. This cable is also the power source for the drive. If you need a longer cable, get a new one rather than using a USB extension cable. If you're connecting to a USB hub, make sure the hub is powered (has its own power supply).

Iomega Prestige 1 TB USB 2.0 Desktop External Hard Drive 34275 Has worked fine so far (a couple of months).

It always needs external power. It has a 3.5" hard drive, whereas the one's that run only on USB have a 2.5" (laptop hard drive). That is the main difference.

It uses an external power supply. It only used the USB and thunderbolt connections for data transfer.

Alex, you asked "Is this drive fully portable, or does it need a power cord?" This external drive is fully portable and needs no external power source. You have one USB to USB connection to your PC or laptop, etcetera, which when connected is assigned a driver by Windows and power is supplied by that one connection in addition to communicating with your PC as an external drive.

This external HD comes with its own power plug, and it has only 2 inputs. One for the USB cable and the other for the Power cord. I am guessing it will only work with the power plug it came with.
