RAID Settings Descriptions
SINGLE MODE Array will show up as two independent drives. This function
can be used if only if two different brands and/or capacities
of HDDs (Hard Disk Drives) are installed.
SPANNING MODE Two HDDs will show up as a single drive with the combined
capacity of both drives. Spanning writes data sequentially
across two drives.
RAID 0 (Striping) Two HDDs will show up as a single drive with the combined
capacity of both drives. Speed and performance increase.
The two HDDs “stripe" data across the two drives. This splits
each piece of Data across both HDDs in segments in a way
that speeds up reading and writing times. However, RAID 0
does not offer any data protection: if one drive fails or is
damaged, all data can be lost.
RAID 1 (Mirroring) The RAID controller creates an extra copy (or mirror) of data
on the two drives. Only a single drive will show up on your
computer, and it will have the capacity of a single drive.
Data is protected from the failure of one drive. If one drive
fails, replace it with an identical drive and the data rebuilds
automatically.
Using this mode requires 2 identical HDDs; the two drives
must be the same capacity, brand and model number.
