For Christmas I also treated myself to a Toshiba 160G external USB hard disk. I decided against Freecom as the one I use at work isn't the greatest quality and I figured a toshiba would be nicer, and I was right, it is a nice little thing, good build quality. So far it has Just Worked and when video editing with my Dell D410 laptop it was certainly fast enough (7200rpm spin speed, faster than the Dell's 5400rpm internal disk).
The video I was working with was 13G long in it's raw .avi format and I only have 20G free in the partition on the laptop, hence I used the external disk. This also had the advantage that I could plug the disk into my desktop system and use that to blow a video CD (Pinnacle Studio doesn't recognise the CD in the laptop). It is running as I type but the rendering is very slow: looks like a frame every five seconds or so. The Dell ran much faster when generating an mpeg to the Toshiba hard disk, maybe five times faster.
I didn't realise how fast the Dell D410 was, or how slow the Desktop is.
I might set up the D410 docking station to use it as a desktop PC and automate backups to the Toshiba which came with some backup software that I haven't played with yet.

I have a 400GB one with OnSpec security or something that only works on Windows and Mac. Do you also have that problem?
