But in all those cases (I have used most of them), there was _some_ way a consumer could acquire hardware (and drivers) to use the tech. It might've been expensive, but I could go out and buy an SATA card, or SCSI 2, or whatever. With A2, so far I have not seen any way any consumer (or anyone, really) could achieve 2000/4000 IOPS. That would be like selling a SATA 2400 drive for 2x the cost of an SATA 600 drive... but not selling any kind of controller that could use more than SATA 600 bandwidth.
