Dropbox stores quite a bit more data than Netflix. Data storage is our business. Ergo, we control storage hardware.
On the other hand, Netflix pushes quite a bit more bandwidth than almost everyone, including us. Ergo, Netflix tightly manages their CDN. That's where they really focus their technical work. Their storage footprint is smaller and less important to optimize to the extreme.
