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.

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).
