EVGA Z390 DARK (131-CS-E399)
The fault tolerance works a bit differently in RAID10 than in others because the array
has nodes with internal redundancy. In other words, although a four drive array can lose
two drives and remain operational, it greatly depends on WHICH two drives fail. If
both drives from the same node fail, then half of the data is gone and the array has
failed. However, every node, regardless of the number of total nodes, can suffer one
internal failure with no adverse effects.

While the Z390 DARK controller will support a four drive RAID10 array, RAID10 can
scale indefinitely provided the controller supports more drives. Every pair of drives
adds an additional mirrored node, which increases the theoretical number of failures the
array can suffer before a loss of data occurs. However, an array can still fail due to both
drives on a node failing.
