I don't think the comparison is Flash vs RAM, I think it's "directly-accessed Flash" vs "Flash on the other side of a PCI-E bus". We don't need anything like a shader for RAM because the bus RAM is attached to is fast. The question at hand is whether the Flash on an SDD is best accessed as a SATA device, DMA Flash over PCI-E (or some new slot technology), or through shader-like cpus on the same card as the Flash.
