MikroTik has not specified if this m.2 slot supports nvme modern disks nor has published a validated list of disks or max capacity supported
i think is necessary to establish a compatibility matrix because some references support m.2 sata and other m.2 pci express (without specifying protocol AHCI or NVME)
That is interesting question that I hope some folks from Mikrotik would come here and shed some light later.
But I would expect that their most high end (and expensive) routers/switches to use NVME. I never actually thought about that when making the purchase as it is so “default” to get M.2 sticks as NVME.
Specially now that we have (at least beta for now) support for containers.
Anyway, will ping back with the results tomorrow once I get the SATA sticks to try out.
Just to update everyone. Indeed, the disk HAS to be SATA in order for it to work (at least by the time I made this post). Got new disks Today and was able to format both as FAT32 just fine. Now I’m looking forward for the containers support to go to stable channel so we can put the images/volumes on them.
As a side note, I still believe someone from Mikrotik team should jump in here and let us know if SATA is just something temporary and they will plan to implement NVME since their chips support it to avoid further questions like this.
Thank you all for the replies!
