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
performance improvement. There are several different levels of RAID, with each one providing a different method of sharing or distributing data
amongst the drives. The DNS-320 supports Standard, JBOD, RAID 0, and RAID 1.
Standard provides a single volume for each
drive.
Although performance is improved, the lack of
any RAID or mirroring means that if one drive
fails, all data on the volume will be lost.
Standard
JBOD
JBOD allows you to create a large virtual disk drive by
concatenating two or more smaller drives together.
It offers no redundancy and limited data protection..
