Hello kevin_intel
I have to disagree with you when say
It is also important to say that the RAID 1 is not intended for performance.
Because Intel himself says otherwise (for reading so RAID 1 is intended for reading performance and RAID 1 is not intended for writing performance) :
The performance of a RAID 1 array is greater than that of a single drive because data can be read from multiple disks - the original and the mirror - simultaneously. Disk writes do not realize the same benefit because data must first be written to one drive, then mirrored to the other.
Best regards,
