RAID
The term “RAID” stands for “Redundant Array of Independent
Disks”, which is a method combining two or more hard disk
drives into one logical unit. For optimal performance, please
install identical drives of the same model and capacity when
creating a RAID set.
RAID 0 (Data Striping)
RAID 0 is called data striping that optimizes two
identical hard disk drives to read and write data
in parallel, interleaved stacks. It will improve data
access and storage since it will double the data
transfer rate of a single disk alone while the two
hard disks perform the same work as a single
drive but at a sustained data transfer rate.
WARNING!!
Although RAID 0 function can improve the access performance,
it does not provide any fault tolerance. Hot-Plug any HDDs of
the RAID 0 Disk will cause data damage or data loss.
RAID 1 (Data Mirroring)
RAID 1 is called data mirroring that copies and
maintains an identical image of data from one
drive to a second drive. It provides data protection
and increases fault tolerance to the entire system
since the disk array management software will
direct all applications to the surviving drive as it
contains a complete copy of the data in the other
drive if one drive fails.
