Section 3 - Configuration
RAID 5 provides data striping with distributed parity, which stores information that can be used to reconstruct data. A
RAID 5 array will be the size of all the combined disks capacity less the capacity of one disk, e.g. If there are 4x 80GB
disks in the array, the arrays capacity will be 240GB (3x80GB).
Implementing RAID 5 on the DNS-343 allows it to continue operating even if one of the disks fails.
The diagram below indicates the operation of RAID 5.
