Let me take a crack at this....

 

Portable drives are external hard drives.  However many are bus powered instead of relying on the 120v power source.  Note some laptops may not have enough amperage so a portable drive takes TWO usb ports to run the drive.

External drive typically need to be plugged in to an outlet as well some tend to not transfer well from computer to computer they like to stay with one computer.

 

A portable is usually powered by the computer itself and can easily move from computer to computer without issue

Re: differance between external and portable HDDs

All portable drives are external drives.  However, not all external drives are portable (enough).  :smileytongue:

 

Some external drives are the bigger, desktop-styled drives that required AC power in addition to the USB cable.  While you can bring it along, you won't be able to run the drive without external power source; so forget about running them on a plane.

 

On the other hand, portable external drives are designed to power via USB.  Therefore, the USB cable is all you'll need to run the drive with the computer.
