There is no lock out of Non-Certified drives. Not supported does not mean it will not work. As it is not supported it is not validated, hence we can not guarantee that it will work. 
Hello, Checking if Dell locked out Non-Certified drives on this controller? I know this was an issue in the past with older controllers/firmware. Are they any features/operations disabled by using non-certified drives on this PERC controller?
