Answer 1

Cheap controllers don't write anything to disk. This is the fate of only expensive RAID controllers.
Cheap - save the settings in their memory.
I endured.
You just repeat the same configuration (RAID-1) in the controller settings - and that's it.
You essentially have completely ordinary drives that you can easily connect anywhere.
