The cost of such drives will not stay so high and the speed will leap drastically
once UAS over USB 3.0 will have become established.  And I am sure that you
don't want every content to go over the network. And far from everywhere will have
the bandwidth to transfer so much data. And of course you assume that you
know where you are going to need your content before you leave or have remote
access to your base system.

You may argue that networked transfers will take up a bigger slice of the cake, but
storage devices are far from dead, even for large amounts of data. And the definition
of largeness is growing.
