What is the best kind of external hard drive to use for extra storage space for my Xbox?

I own an Xbox and PS3 and I was looking into buying an external hard drive to store games on, mostly for my Xbox. It is running out of space and one or two more games and I won't have enough space. I was looking into buying a 1 or 2 TB external hard drive, and I was wondering if there are hard drives that work better than others with the Xbox. I will also be using it with my computer, which is why I'm not going for the Xbox specific external hard drive.
