I'm buying an external hard drive for a friend. He is picky so I need to make sure I get a good one! I know that I need one that has the faster revolution speed and at least 200-250 GB. He is going to travel with it so it should be small, durable, and from a reputable company with a good warranty. It isn't going to be just for document storage and the like. I think he may want to use it to hold music, video and such so that he can entertain himself while on the road. I'm not sure what else you need to know. I'm not particularly stupid (I don't think) but this isn't my area. He's on this site all the time so I know advice from you guys will be the best I can find.
