I answered "the same", and was surprised to get it wrong.
But, having thought more, doesn't the answer depend on how many drives there are? I was assuming four drives, A, B, C and D, as that's the only time I've used RAID10. I'm also assuming the terminology follows this: In RAID 0+1, I stripe A & B and mirror the stripe set onto C & D. In RAID 1 + 0, I have two mirrored pairs, A & B and C & D, which form the two stripes. I have never seen a RAID controller that explicitly states RAID 0+1, so I'm never sure which way round it is handling my four drives.
In either configuration, you can only lose two disks, and even then only the right two.
Or have I got it all wrong ... again?!
