To be honest, I had enough of the OS 5. I can say i am finally back to the OS 3 version.
It could however, be killing the board in this thing, it might not actually be killing the drive itself. I would pull the drives and checking them before assuming them to be dead. Even though, my WD Reds were running kinda hard and loud before choosing to go ahead and place a fan atop the system, and then ultimately downgrading back to OS 3. With the external fan on mine, It took the drive temps from 54 to about 41. The drives were still hitting pretty hard for a few minutes, but have now went back to being their quiet self.
