I still have the error "does not support 4kn drives" : I can't create the L2 Cache...
With ver 4.1.0, you can create an L1 cache for a 4Kn drive. You must wait a bit longer to be able to create an L2 cache on a 4Kn drive.

"You must wait a bit longer to be able to create an L2 cache on a 4Kn drive" : does it mean that it will come in a future version of primocache ? When can we expect it to be available ?

Yes, we will support 4Kn drives as level-2 storage in future. However, in your case, I don't think you need to create a mirror of two SSDs as level-2 storage. The available cache size is reduced to half if you use the mirror type. The simple type should be good for level-2 cache.
PS. If you want to overcome this 4Kn issue, you may just use Windows Dynamic Disks to create a spanned volume based on these two SSDs, instead of using Storage Spaces which create 4Kn drives.

Thanks for the suggestion, I'll look into dynamic disks then !
