http://www.amazon.com/Seagate-FreeAgent-External-Hard-Drive/dp/B0012YW1AU I'm taking a Digital Media class on my study abroad trip this semester and one of the requirements for the class is that "Students will also need a portable external drive for storing files, a 120 gigabyte drive will be perfect." I'm not computer savvy whatsoever but would this be ideal for my class? We will be working on video projects and such. Also, I have a MacBook.. would it still work/be ideal with a MacBook? Thanks guys!
