Ahhh, I think I get what you mean. So given that it works that way, and given that our previous approach of pre-overprovisioning the drives didn't work ( http://mangolassi.it/topic/4614/how-should-i-determine-exact-over-provisioning-levels-for-1tb-samsung-850-pro-ssds-to-be-used-in-a-raid-10 ), is there just no way to do this?
I have a feeling that there is not. If you are going to do this, you need to control the RAID provisioning. But I am not sure if the RAID card is going to work with you on this or cause problems. That would depend very specifically on the drives and the controller and how they interact.
