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".
