My personal laptop I'm typing this post on has an 89.1 GB hard drive, plus an additional 80 GB on an external hard drive. However, I use the external one as a back-up to what I already have, not as a supplement. If all 9 of the episodes I downloaded were 1.5 GB, that would be 13.5 GB. I'd still have space to spare, but such as that would add up quickly, especially if I downloaded more episodes in the future.
