It does not make sense for SATA SSDs to be priced 1/3 cheaper than NVMe as they use the same NAND flash as NVMe drives. NAND flash is a commodity so doing artificial segmentation with it is tricky. Controllers, I imagine, are cheaper since SATA is capped at 6Gbps (much lower than NVMe) but even if a SATA controller were half the price of a top end NVMe one, the controller would need to constitute 2/3 of the BOM cost of the SSD to enable a price reduction like that, which it does not. | ||||||||

SATA tops out at 600MB/s meaning you can use cheaper denser NAND. | ||||||||
