Thank you for your correction. I had this doubt from time ago. but i was inclined to the wrong answers.
A question out of topic: ¿A raid-5 of 5 disks has the same performance for partial stripe writes than a raid-5 of 10 disks? If the parity is "striped" across all disks, then a raid-5 of 10 disks must have better performance.
