Who really uses more than 320GB

[comp builder]

i am sitting here wondering if people who buy these huge hdd's (320GB etc) really use them. I dont know anyone (including me) who has ever used more than 60GB and if you put hundreds of pics etc on your comp then wont it slow it down loads?????

i dont know i just thought that the more stuff you had on your computer (pics, songs etc) would make it run slower but im oviously wrong, oh well
