I'm very much a fan of open channel flash. My understanding is that the Open Channel flash people when they tried a decade ago basically got told no by drive makers, that the drive makers weren't interested in becoming commodity vendors, and were intent on keeping product lines somewhat as they were. I wish I had some links to share to back this up, but that's basically my recall. ZNS and then FDP was sort of a compromise to give people some of the wins they were looking for, while basically not disrupting the product.

FDP is a very minimal addition of control. But yes it is another box to ticket, is another place to upcharge. Yet still, we're only just seeing mainstream products emerge. Kioxia's CM10 for example. https://www.techpowerup.com/351218/kioxia-introduces-first-p...

I'm hoping that the need is great enough to break the industry control. I think for a while the market felt relatively well enough served such that it was unclear whether clear wins would actually result in customers. With AI need for speed, I can definitely imagine incredibly crazy CXL controllers or what not, that allow low latency acces to many many open channel flash systems. Wouldn't that be a thing.

Again though, FDP is such a ridiculously tiny add, and it helps SSDs so much for so many use cases. I really hope it becomes an expectation, not a feature, sooner rather than latter.

Edit: happy to see a new group has shown up asking for open channel flash, Open Flash Platform. https://openflashplatform.org/
