I've been googling around, but can't seem to find a solid description.
I realise Nvidia's 0+1 requires 4 drives. 2 for striping and two for mirroring. However here is the question.
Are the mirrored drives just mirrors of disk0 and 1's stripe? Or is it a mirror of the complete data (times two)?
Does that make sense?
Disk 0 - Stripe
Disk 1 - Stripe
Disk 2 - Mirror of Disk 0
Disk 3 - Mirror of Disk 1
or
Disk 0 - Stripe
Disk 1 - Stripe
Disk 2 - Mirror of both striped drives (into functioning single disk)
Disk 3 - Mirror of both striped drives (or mirror of Disk2)
