You could have 2 mirrors (3 copies) as well, striped over the disks.
That would survive two disk failures.
Or you could have 1 mirror (2 copies) whereby one copy is over
2 disk while the other copy is over 2 disks. You could only survive
one disk failure though.
Again, you only need 2 disks for RAID-0+1. You stripe and then
mirror to the other disk that does not contain the stripe. It can survive
one disk failure.

I would be very curious to know how you're running RAID10 with 3
disks. Is drive3 twice the size of 1 & 2 so you can mirror both disks
on different partitions? What does /proc/mdstat look like?
