Section 3 - Configuration Advanced 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. 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 it's smallest member disk. Because the data is stored on multiple disks, RAID 1 provides fault tolerance and protection, in addition to performance advantages. D-Link DNS-343 User Manual 26

D-Link DNS-343 User Manual
Section 3 - Configuration
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.
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 it’s smallest member
disk.
Because the data is stored on multiple disks,
RAID 1 provides fault tolerance and protection, in
addition to performance advantages.
