Motherboard controllers that support RAID0+1 (such as certain 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 and the backend calculations needed to maintain the arrays,
whereas RAID0+1 only increases stripe size.
