I wish they made a new connector for NVMe. M.2 is limited so hard by PCB size and room on the mainboard. I demand a cable and a 2.5" form factor.

But not any kind of cable, it needs to be something special. Let's bring back the old IDE cables and use them for NVMe.

Nahh it already exist what he want but it only used in the server space.  There was a few Consumer motherboards that have it built in but for most part only found on server boards.

It called U.2. and it carries X4 PCI-E data across a cable to SSD that support it (I think the actual cable is called oculink 2).  The Intel Optane drives use them.  You can get add in cards to add support for it to the motherboard.

In the end through would not fix vivster problem.  It not space that limiting number of Nvme drives but limits on the number of available PCIE lanes.  I got 4 M.2 slot on my motherboard and it came with a add-in card to let me add 4 more so I could have 8 M.2 drives if I wanted.  I got that option because threadripper platform has the PCIE lanes to spare.

On Ryzen you dont see that because of limits on PCIE lanes, if more was available they would find a way to fit more drives in.
