The issue is that as dumb as it is, SATA ssds are still a big part of the consumer market.

Even though nvme isn’t appreciably more expensive to make, it’s still used as a “premium” product., and SATA is a product tier to capture budget market whole protecting their more premium market.

This move is a clear symptom of the real issue. Manufacturers shifting as much capacity as possible towards big datacenter buildouts at the expense of starving every other market for these products. Trillions of dollars that will pay whatever it takes competing with a more rational market
