While both RAID 0+1 and RAID 10 have good performance
characteristics... RAID 10 is much, much more reliable.
Good RAID 10 solutions generally are HW based RAID.
Though I have used Veritas in the past to do a RAID 10.
Not sure exactly how to perform a RAID 10 in software
with Linux.  A single drive failure in 0+1 invalidates
the entire column.  With RAID 10, there's the possibility
of tolerating multiple drive failures.
