I think the next logical step in servers would be to remove the traditional
hard drive cages and put SSD module slots that can be hot swapped. Imagine
inserting small SSD modules on the front side of the servers and directly
connect them via PCIe to the motherboard. No more bottlenecks and a
software RAID of some sorts would actually make a lot more sense than the
current controller based solutions.
