You are wrong. raid 10 and 01 are different.
_____o_____ __X__ __Y__ | | | | [A] [B] [C] [D]
RAID 10: A+B and C+D are two raid 1(X and Y) the union 'o' is a raid 0.
RAID 01: A+B and C+D are two raid 0(X and Y) the union 'o' is a raid 1.
Which is why you almost never find references to "RAID 01"... it's confusing. What you describe here as RAID 01 is more correctly known as RAID 0+1, indicating that you have RAID 0 sets which you then mirror. RAID 10 is, as mentioned, mirrored pairs which are then striped.
