I save everything I download. Why, because I worry that someday the government or ISPs will clamp down on everything or just hardcore stuff. Or the Internet won't be anonymous anymore. I would never download porn at work where my idenity is known, I wouldn't be able to do it if my ISP knew who I was (I don't have a monthly fee ISP
).
I measure my collection in terabytes though. I think it is around .4 - .5 TB right now.
