At my company we had two times now a disk in a RAID 5 broke and the array could not restore itself and had to use backups to continue working on another server. An identical issue with RAID 10, never cause any issues or significant downtime.
I noticed this post and had to respond. In a properly configured RAID 5, a single disk failure would not cause a failure of the array. And even if there was a failure of the writing of the data to the replaced disk, no one would have known it because the array would have kept chugging along like nothing happened.
So, I'm wondering if your aversion to RAID 5 is simply based on misunderstanding? What you've described cannot happen in the real world.
