I did some tests to check if everything will go alright with a failed disk:
- I set as failed and removed /dev/sda partitions (2).
- Rebooted (boots alright)
- Added the two partitions back to the arrays. Rebuilding the arrays.

Speed tests were made with dd (2GB file)
Is there something I miss? It looks to me like some setting problem.
