External HDDs are very hot these days. The reason is simple: they offer a good cost per GB ratio.
In the last years there were 3 main trends:
- the prices per GB went down
- the capacity increased
- the miniaturization made the HDDs smaller and lighter.
Now the prices are great. For a 1tb external hard drive you will pay only £59.99. I remember when I wanted to get an external hard drive (1 TB) not too long ago, the price was around £200.
For extra portability you can opt for an extra portable hard drive. I use an Iomega eGo Portable 320GB Hard Disk Drive 5400rpm USB 2.0 8MB.

It is small and light and it fits in my pocket. When I need extra space I use an western digital 1tb external hard drive.
I have had both the Western Digital and the Iomega eGo Portable hard disk drives for 2 years and both work great.
