RAID0 (One or more HDDs 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 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 (= 6).
