That was basically the original idea behind vertex buffers: to hold static data in video memory so that's faster to access by the GPU (mostly in the sense of avoiding data transfers from SYSMEM).

Similar idea behind ProcessVertices(). If you wanted to draw with dynamic data, you'd use the non-VB Draw[Indexed]Primitive variant.
