In YaST to do it you have to use RAID 1 then RAID 0, however if you do it via command line it is much more flexible and can even use uneven numbered drives. Here’s a link on how to do that with decent settings:

Also, you should not do a mirror of stripes, but rather, a stripe of mirrors.
Otherwise, you lose some of the robustness in the tolerance of failure. If you stripe first, a loss on the RAID 0 side will wipe out your data, so any disk loss will result in a failure of the set. If you lose any 2 disks you lose all your data that way. However, with a good RAID 10 you can lose up to 2 non adjacent drives.
To explain, let us assume you have 4 drives for your RAID 10. You have A, B, C and D
A and B become /dev/md0, a RAID 0
C and D become /dev/md1, a RAID 0
/dev/md0 and /dev/md1 become /dev/md2, a RAID 1, of 2 RAID 0, (10)
You lose drives A and D and now you have no data
Now, my scenario works like this:
A and B become /dev/md0, a RAID 1
C and D become /dev/md1, a RAID 1
/dev/md0 and /dev/md1 become /dev/md2, a RAID 0, of 2 RAID 1, (10)
You lose drive A and D
B contains all the data that A had. D contains all C had, you are still running.
