Sorry, that is raid0 on top of raid1.  With raid1 on top, then after
the first disk failure, the second failure has a 66% chance of
destroying the data.  With raid0 on top, the second failure has only
a 33% chance of destroying the data.

Raid10 is a way of striping the data with redundancy in a single layer.
