RAID 10 is the best if money is no concern. You have one stripe with RAID 5 then mirror it against another stripe that's RAID 5. Getting there, yes raid 10 is the way to go but the description is of 0+1 NOT 1+0. In raid 10 you create lost of small mirrors THEN stripe them. E.g. six disks 1,2,3 and A,B,C become mirrors 1,A -2,B- 3,C then create the stripes so in 1+0 if you lose 3 disks 1,B and 3 for example you still have a live stripe set. in 0+1 you would have a dead system.
