this is often the case for new hardware specs/protocols..
see also: any SATA/SCSI rev N+1, TCQ/NCQ, UASP, PCI n+1, etc.
- geerlingguy 7y agoBut 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.
- megous 7y agoIt should be possible to patch the kernel. If I had an A2 card, I'd try. It's probably just a question of detecting card features on card plug-in and sending a command to enable the cache. Spec/code is open. I'm just sort of surprised noone tried it yet.
