Adding a JIT to the mix only makes the problem worse, its a question of resources, your not going to fit all that code into a tiny SD micocontroller which has a very limited CPU/ram footprint even in comparison to sata SSDs. The resource availability takes another huge jump when you move to a full blown "array", which not only has all this additional disk mgmt functionality, but its going to have network mgmt functionality, etc. Some of these arrays have full blown xeons/etc in them.

Plus, disks are at least partially sold on their performance profile, and your going create another problem with a cross platform IR vs coding it in C/etc and using a heavyweight optimizing compiler targeting the microcontroller in question directly.

You also have to remember these are effectively deeply embedded systems in many cases, which are expected to be available before the OS even starts. Sometimes that includes operating over a network of some form (NVMe-OF). So it doesn't even make sense when that network device is shared/distributed.
