> The same MTP head could also be used to speculative prefetch the expert weight residing on the SSD. If the expert weight can be preloaded before the GPU actually need them, the speed penalty from VRAM cache miss will be quite reduced.

When using SSD streaming, the GPU is practically always waiting for the SSD to fetch the right expert, rather than the other way around. There is basically zero slack on the SSD side, so I'm not sure how "prefetching" is supposed to help. It would mostly hurt by fetching the wrong predicted experts, which already makes conventional MTP practically unhelpful for typical (not widely batched) SSD streamed inference.
