RAID 0 MODE
RAID 0 - Striping: Two HDDs will show up as one large single drive but speed performance will boost up.
The two HDDs will write Data in “column” effect. This form of array splits each piece of Data across both HDDs in segments.
Data are store between first HDD and second HDD. While the HDD is stripe in writing, the next head of next HDD is move to next track to write. The Data is writing
without any form of data-checking. Once one HDD is damaged and all data can be lost.

Non-RAID: (Single Mode) Computer will show up as two independent drives. This function can be used if RAID is not required, if one HDD is installed
or two different barnds or capacities of HDD are installed.
SINGLE MODE
RAID 1 MIRRORING MODE
RAID 1– Mirroring: Using this mode will require 2 identical HDDs; meaning they must be the same capacity, brand and model number. Under RAID1,
it will create an extra copy (or mirror) set of data to second drive. The backup data are more important for safe keeping and the available data only show up
in one large single drive. This is useful when first HDD fails and it can be replaced by second set of identical data instantly.
4TB
JBOD MODE
RAID 0 - Spanning: Two HDDs will show up as one large single drive. Spanning is an array (not RAID) that is written sequentially across two drives.
