At least some vendors are already doing that.  The Dell 730xd will take up
to 4 PCIe SSDs in regular hard drive bays -

For another list I just estimated how many M.2 SSD modules one could
cram into a 3.5" disk case. Around 40 w/ some room to spare (assuming
heat and connection routing aren't problems), at 500GB/each that's
20TB in a standard 3.5" case.

It's getting weird out there.


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.
