Storage Tiering is the answer
For the storage market these are very interesting years. Since decennium the performance gap between slow mechanical disks and processors was increasing. With flash storage we can fill partly the enourmes performance gap that is there. However it is nonsense to think that all storage will be flash. 

We will see a more diverse market where storage tiering is key. Big data that doesn't require performance will be on media that has a lower price per gigabyte as well as archive and backup data.

However a new and even faster storage tier will be more important. RAM. Another interesting fact is that sever memory is getting cheaper very fastly. That gives room for another improvent, especially in the virtualized world. Since server memory is by far the fastest storage, it is predestined to serve for computing related tasks. Where at this moment virtualized desktops, servers and applications are located on storage, this will move more and more into RAM based memory in the near future.

A company that deliver already this technology today is Atlantis Computing with there ILIO for VDI and USX for virtual servers. At this moment RAM is non persistent which have some disadvantages, however IB is at this moment working on persistent RAM.

Ahead in the future we should se a tiering modell that offer a wide range of storage tiers. RAM for the highest IOPs demands as Tier 1, Flash and SSD as caching Tier or High Availabel persistent storage tier and SAS for low cost low performance data access.

Re: Is all storage about to move to Flash?
Pure has an impressive list of backers. I would guess they suffer from the "no one ever got fired for buying [insert established vendor here]" syndrome when selling to typical enterprises, with the established vendor being EMC via its XtremIO purchase.

Still, nothing like competition!

Is all storage about to move to Flash?
Dietzen actually thinks all storage, 100%, is destined to become Flash-based because of its lower power requirement -- no moving, mechanical parts. But getting the backups, archivals and object stores into solid state will take quite a bit longer than the highly available storage that benefits from speed of response.
