RAID 0 (Striping)
RAID 0 (Striping) is a performance-oriented, non-redundant data mapping
technique. It combines multiple hard drive/SSDs into a single logical System.
Instead of seeing several different hard drive/SSDs, the operating system sees
only one large drive. Striping splits data evenly across two or more hard
drive/SSDs simultaneously, dramatically increasing performance.
Striping can be implemented in hard drive/SSDs of differing sizes, but the
storage space added to the array by each hard drive/SSD is limited to the size of
the smallest hard drive/SSD. Although Striping is an easily implemented and
simple configuration, Striping should never be used for mission critical
applications. The speed of operation is fast in comparison to other RAID modes.

In Striping mode, if one hard drive/SSD in the RAID System fails, all data in
both installed hard drive/SSDs will be lost.
RAID 1 (Mirroring)
RAID 1 (Mirroring) consists of at least two (2) hard drive/SSDs storing duplicate
copies of the same data. In this mode, the data is simultaneously written to two
(2) hard drive/SSDs. Thus, the storage capacity of a two-disk array is combined
into a single disk and the capacity is limited to the size of the smallest hard
drive/SSD. The speed of operation is average in comparison to other RAID
modes.
