I was just playing around with Google Trends. A great tool to compare search popularity between search terms.
How much impact storage startups really have on the market is hard to pin down, but the search popularity of individual brand names does provide some perspective.
Below, I compared worldwide search popularity between Storage Startups over the last 6 years. I looked at three groups; Boxed Storage, Software-only Storage and Server-side Caching Solutions. Then to put the Startup scene in some perspective I compared the most popular of each group to storage giants EMC and Netapp.
Boxed Storage: Nutanix, Nimble Storage, Pure Storage, Tintri, Skyera
