All of these factors were taken into account.
Not sure if you are a Gartner client, but if you can please read the Critical Capabilities for Solid State Arrays http://www.gartner.com/document/2834717, Also, please have a look at this post from Chris Mellor; http://www.theregister.co.uk/2014/09/13/gartner_ranks_startups_ahead_of_emc_hp_and_ibm/. Gartner produces two reports for two different audiences. The MQ reviews companies, that is vendors on their ability to succeed. The Critical Capabilities (CC) reviews vendors products on their suitability for workloads and the products features. There are links to them here http://blogs.gartner.com/valdis-filks/2014/08/29/solid-state-array-magic-quadrant-and-critical-capabilities-published/. The discussion here is more orientated to the technical aspects of solid state arrays, so you should really reference the CC, which does explain the points which you mention above. If you are a Gartner client please organise a call and we can have a chat.
