You wrote: Every competing storage system (NetApp, Dell EMC, HPE) uses commodity SSDs. Each SSD contains its own Flash Translation Layer, a firmware layer that makes NAND flash behave like a spinning hard disk. This compatibility tax is expensive: each drive embeds its own DRAM controller, loses roughly 20% of raw capacity to overprovisioning, and remains a black box to the array operating system above it.
