External HD has become very much in demand because it can store a high capacity of data. The best ones are the portable varieties. I was given the WD Elements Desktop for my birthday by a friend. She said it's time to bring all my files out of different flash disks and to store them in one external HD. It's actually cool. It has a 2 TB capacity and you can use it through USB 2.0. It's plug and play so there's no hassle. I find it simple and very reliable. I even checked it out at Western Digital and found out it's cheap as well. Am thinking of giving one to my sister for her birthday.
