RollTide14, you may well have a point, and thanks for causing me to see the statement from another perspective. The position of proprietary or custom hardware having difficulty is true of some and not as true of others (Hitachi makes their own FMDs, as does IBM for some of their TMS-descended systems). It seems the sticking point on a lot of these historically has been that the hardware and the protocols necessary to leverage it were proprietary. With this system, it seems that Pure has built a drive, but is using the industry standard NVMe protocol to address the drive. In a way, Samsung, WD, Toshiba, and Intel produce proprietary drives with open protocol connectivity. Certainly the secret sauce of each of these manufacturers is in their firmware, true?
I'd be interested to see if the economies of scale that the drive manufacturers can leverage ultimately mitigates against Pure building their own drives in the future, and whether or not their system will permit the flexibility to adopt lower-cost mass-produced items in the future?
