Distributed parity requires all drives but one to be present to operate;
drive failure requires replacement, but the array is not destroyed
by a single drive failure.
Upon drive failure, any subsequent reads can be calculated
from the distributed parity such that the drive failure is masked
from the end user.0 The array will have data loss in the event
of a second drive failure and is vulnerable until
the data that was on the failed drive is rebuilt onto a replacement drive.
Note: The computer will detect 2 drives.

Striping is a method of concatenating multiple hard drives
into one logical storage unit.
It is the automated process of writing data across
multiple drives simultaneously.
Striping is used to increase the performance of disk reads.
The multiple hard drives will write data in “column” effect.
If one drive in a striped set fails, all of the data
in the stripe set is lost.
Note: The computer will detect 1 drive.

2x Raid 0 Striping, is the same like Raid 0 striping.
Note: The computer will detect 2 drives.
