|Sorry Lordmanhammer but you have those reversed.|
The way I have found to remember this the best is you start with the last number and go forward.
So 0+1 is a mirror [raid1] of a stripe set [raid0]
In turn, raid 10 is a stripe of mirrors.
You can lose a single disk in each mirror set of a raid 10 and still be operational.
This is not the case with raid 0+1 because after the first disk failure you are down to being a stripe set which has no failover.
Answers are only as good as the information you provide.
