RAID 10 vs RAID 01

The differences between Raid 10 and Raid01 are as follows:
RAID 01 is also called RAID0+1. RAID 01 is first stripe it  (RAID 0) and then mirrored (RAID 1).
RAID 10 is also called RAID1+0. RAID 10 is first mirrored (RAID 1) and then stripe it .  (RAID 0). 

like the below figure show , in the Raid 10 , the data was saved on disk as A1 A1 A2 A2 , in the raid 01 , the data was saved on disk as A1 A2 A1 A2 .  

Dear,

Here are some tips about RAID01 and RAID10.

RAID 0+1 (Mirrored Stripped)

In this RAID level all the data is saved on stripped volumes which are in turn mirrored, so any disk failure saves the data loss but it makes whole stripe unavailable. The key difference from RAID 1+0 is that RAID 0+1 creates a second striped set to mirror a primary striped set. The array continues to operate with one or more drives failed in the same mirror set, but if drives fail on both sides of the mirror the data on the RAID system is lost. In this RAID level if one disk is failed full mirror is marked as inactive and data is saved only one stripped volume.

RAID 1+0 (Stripped Mirrored)

In this RAID level all the data is saved on mirrored volumes which are in turn stripped, so any disk failure saves data loss. The key difference from RAID 0+1 is that RAID 1+0 creates a striped set from a series of mirrored drives. In a failed disk situation RAID 1+0 performs better because all the remaining disks continue to be used. The array can sustain multiple drive losses so long as no mirror loses both its drives.

This RAID level is most preferred for high performance and high data protection because rebuilding of RAID 1+0 is less time consuming in comparison to RAID 0+1.
