I remember reading about samsung scaling back NAND production as not to depresss the price. I am in the market for a new setup as I move, and I saw that 4tb SATA and m.2 pcie4 were similar price, with the 2280 drives actually being slightly cheaper.
Have we reached the point where the cost of the controller is an afterthought?
Most new laptops and mobos have pcie m2 slots these days. So it makes sense that the market has gone that way. I think sata will stick around for a while mostly for bigger basic ssd drives and the low end of the market.
