But what I am trying to understand is, how to benchmark the

Perhaps you could use dm-dust to make an unreliable block device
from a real device?

That seems uselessly complicated to me. What about this ?

- benchmark the array in the clean state
- fail and remove a drive
- benchmark the array in the degraded state
- add a new drive and start the resync
- benchmark the array in the resync state
