EVGA X299 Micro ATX 2 (121-SX-E296)
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.
RAID 10 (4 Drive)

L-Drive = DATA-A
L-Drive = DATA-AB

While the X299 MICRO ATX 2 controller will support a four or six 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.
