What is RAID?
RAID, short for Redundant Array of Independent Disks, is a combination of two or more disks with the aim of providing fault tolerance and improving performance. There are
several different levels of RAID, with each one providing a different method of sharing or distributing data among the drives. The DNS-346 supports JBOD, RAID 0, RAID 1,
RAID 5, RAID 10 and Standalone.
RAID 0: RAID 0 provides data striping, which spreads out blocks of data
over all drives, but does not provide data redundancy.
Although performance is improved, the lack of fault tolerance
means that if one drive fails, all data in the array will be lost.
RAID 1: RAID 1 provides mirroring over multiple disks, with the same
read/write speed of a single disk. A RAID 1 array can only be as
large as its smallest member disk.
Because the data is stored on multiple disks,
RAID 1 provides fault tolerance and protection, in addition to
performance advantages.
