If you do anything with video/photo's and many other types of things the space adds up quickly. I had 2TB filled with just games that I had purchased. Just my steam folder alone is pretty massive. Files are getting a lot larger with the amount of storage we have access to. Just compare a floppy disk to a CD to a DVD. You've only used floppy's and someone comes up to you and shows you a CD... "WOW! what legal use could you POSSIBLY have for that!"
