It is incorrect to state Raid 10 is the same as Raid 1+0 which is a confusion with Raid 0+1.
Raid 10 is always referred to as raid 10 never as 1+0.
Raid 10 is a mirror of stripes not “stripe of mirrors”
Raid 0+1 is a stripe of mirrors
You are confused between Raid 10 and Raid 0+1
Raid 10 can sustain a TWO disk failures if its one drive in each mirror set that fails.
Raid 0+1 with the loss of a single drive reverts to a Raid0 array.
Please correct your misinformation. Thanks
