RAID0 (One or more HDD is required.)
Multiple HDDs are grouped and constructed as one unique logical device.
Data is recorded in a dispersed manner and the write and read performance of the HDDs
is high.
RAID1 (Two HDDs are required.)
The HDDs are mirrored images of each other. The same data is always written to both
HDDs. Therefore, if one HDD is damaged, the operation can be continued by the other
HDD.
RAID5 (Three or more HDDs are required.)
Multiple HDDs are grouped and constructed as a single logical device. Data and the parity
are recorded in the grouped HDDs in a dispersed manner if one HDD is damaged, the
operation can be continued by the other HDDs.
Hot Spare (Can be used if RAID1 or RAID5 is selected.)
Hot Spare is a spare HDD in stand-by; when one HDD is damaged the hot spare
automatically goes on-line.
HDD Assignment
Select the number of HDDs for the RAID configuration from the list. When "MAX" has
been selected, the RAID array is structured with the maximum number of HDDs (= 4).
