I wish it would. Most of the research and stuff so far has either put the file system into the disk firmware (upgrade hell). Having a disk which talked entirely about
read(handle,offset, length) write(handle, offset, length) alloc(handle, near_handle, length, otherhints...)
might well work out rather better. It also allows the disk to do fairly major relayout of data as it learns usage.
