I think we're headed to a future where fast, permanent storage is mostly in a small slot (similar to MicroSD) form-factor, just like scifi/future movies of old.

I think we're headed to a future where fast, permanent storage is mostly in a small slot (similar to MicroSD) form-factor, just like scifi/future movies of old. The slots will get smaller, hopefully there will be more than one on tablets and whatever passes for laptops/desktops. And I'm sure they'll figure out a way to converge these slots and USB-C into something else new to make everyone buy all new dongles and adapters "USB-D."
