Also as a side note. Nvidia does have their GPUDirect Storage for their enterprise customers back in 2019 that does allow their GPUs to directly access the storage while completely bypassing the system memory if needed... I am sure MS's upcoming DirectStorage solution for Series X and PC does something very similar.
