Hi Joel,
1+0 is mirrored first and then striped.
0+1 is striped first and then mirrored.
RAID 1 is only mirrored disk, and RAID 0 is for stripe only. The above
combination would identify the same in that order. Yes RAID 1+0 would
perform better in general and when recovering from a failure. Correct me
if I am wrong, or you meant the same.
Thanks!

Geez. I called them wrong. If you read the conclusion you would be confused.
The correct terminology for this is:
10 is striped first and then mirrored (a striped mirror), and
01 is mirrored first and then stripped (a mirrored stripe).
