>How many more movies can Netflix support with these new drives?

Netflix doesn't do their own hardware, they use AWS. One can also assume that the cost of the content far outweighs the cost of delivery.

The AWS marketing folks don't get paid enough.

They do, however, use AWS to run most of their service:

This is untrue. AWS is used for some things, but not all.

I've heard certain details I'm unwilling to share, but some of what they do is public (https://www.netflix.com/openconnect/hardware).

Also, they pay developers to work on optimizing network performance of FreeBSD for this custom hardware.

AWS' monthly costs approach cost of ownership. Netflix's costs in providing service are a substantial amount of their spend. AWS works well for Netflix because they have a workload that varies on a daily and weekly basis - by using AWS' excess capacity during peak times, Netflix is able to save money over owning their infrastructure outright.

Given AWS is one big Tetris game, jamming instances in where they fit, this has worked out well for both parties. Until now, with 'now' being defined as the dawn of distributed commodity compute.
