Portable Hard Disk Drive. A small chassis with which you can put your 2.5 inch HDD in. This can connect to your computer via USB cable (maybe firewire aswell :) and allows access to it like any other storage device.
1. "My HDD died on me last night, thoughtfully though I had saved all of my important files on the PHDD."

2. "These PHDD things are great, while they are bigger than a Pen Drive they are still very portable and they hold a great deal more DATA whilst being alot
more CHEAPER".
