Do You Really Need All That Hard Drive Space?

We stream a lot of the stuff we used to (still do!) hoard, like movies, TV shows, and music. So, that begs the question: Do we still need that much hard drive space? Or SSD space or onboard phone storage? I used to lust after 1TB drives in laptops and 64GB of flash storage in media players and phones. But these days, that just seems nuts unless you're a professional. What about you guys?
