EVGA X299 Micro ATX 2 (121-SX-E296)
The Good-

Fastest of the standard nested RAID types

Performance scales with drive count.
The Bad-

Build times can be substantially longer than RAID10 due to the volume of data
being moved, and is typically close to the rebuild times of RAID5.

Low space efficiency, only 50% of total drive capacity is usable in the array.

1 drive failure drops a full stripe set.
RAID 0+1 (4 Drive)

Motherboard controllers that support RAID0+1 (such as on older generation EVGA
motherboards) will generally support 4 or 6 drive arrays of this type; other controllers
can allow this array type to scale indefinitely. Each pair of drives adds to the drive count
for the stripes and increases the theoretical volume of failures the array can suffer before
a loss of data occurs. However, this type of array can fail due to any two drives on
different stripes failing at once; this is RAID0+1's main drawback. Theoretically, at six
drives and above, RAID0+1 should have slightly faster read/write speeds compared to
RAID10 because the stripes are larger without the overhead of an internal mirror. This
is because RAID10 increases both the number of mirror sets as the array scales upwards
